The Story of Marlow Bend (1860, Appalachia) — The Underground People Who Came Up Only at Night

On the morning of October 14th, in the autumn of 1861, a Methodist circuit rider named Elias Beckwith rode into a small Appalachian settlement called Marlo Bend and found every single house standing open, every door, every shutter, every gate on every animal pen. The livestock were still in their pens, calm and fed.

Bread was still cooling on kitchen tables. A kettle was still warm on one of the stoves, but there was no one there. Not one man, not one woman, not one child. 47 people had lived in Marlo Bend the night before. By sunrise, every single one of them was gone, and the only thing they had left behind was a message carved into the wood of the meeting house door.

It was written in a language that Elias Beckwith could not read, and that no linguist consulted afterward could identify, and it was carved from the inside. However, what Beckwith found in the second cellar of the old Marlo house is what actually changed everything because it proved that the people of Marlo Bend had not simply vanished. They had been called down.

Part of what we are about to uncover in this story is that Marlo Bend was not unique. There are places like it scattered across the ridge country of the eastern United States. Places that had names on old survey maps and then quietly stopped having names. Places where the road just ends and nobody remembers why.

To understand what happened in Marlo Bend and to understand why it matters even now more than 160 years later. You have to first understand where Marlo Bend actually was. And this is where the story starts to get strange even before the disappearances. Because Marlo Bend is not on any modern map. It was never incorporated.

It was never given a post office of its own. It is not listed in the 1860 federal census, even though we know from private letters and church records and freight receipts that at least 47 people were living there in that year. Most of what we know about the settlement comes from the papers of the Beckwith family, from a bound ledger kept by a general store operator named Zebulun Foss who lived one valley over, and from a series of survey notes made by a young engineer for the Baltimore and Ohio Railroad, whose surveying party passed through the region in the summer of 1858.

Everything else, every other written trace of the place is gone. Whether that is coincidence or whether that is something more deliberate is a question we are going to keep coming back to. Marlo Bend sat in a narrow B-shaped valley along the upper reaches of what the settlers called the Yellow Snake Creek in the western Appalachian Range in a stretch of ridge country that was already considered remote by the standards of its day.

To reach it, you had to leave the last real wagon road at a crossroads called Danver’s Fork. Follow the creek south for about 11 miles through timber so heavy that the sunlight barely touched the ground. Cross the water three times at shallow fords and then climb a short switchback trail up over a shoulder of exposed limestone.

On the other side of that limestone shoulder, the land opened up into the bowl and the bowl was Marlo Bend. It was almost perfectly circular about a mile across, ringed on all sides by ridges that rose 400 to 600 ft above the valley floor. In the center of the bowl, there was a small stream, a scatter of cleared fields, an orchard, a burying ground, a meeting house, and 11 cabins.

The soil in the bowl was good, better than it had any right to be at that elevation. The stream ran clear, even in dry summers. There was a natural salt lick at the northern edge of the fields that drew deer down out of the ridges every autumn. And the ridges themselves were riddled, absolutely riddled with caves and sink holes and vertical shafts that opened up into the limestone beneath.

This is important because the limestone in that stretch of Appalachia is the kind that carves itself out over time. Water eats it, ice eats it, and what it leaves behind is a network of hollow spaces underneath the surface that in some places runs for miles. A brief note on the geology because it turns out to matter.

The particular stretch of limestone that underlies Marlo Bend is part of a formation that geologists now call the ridgeback cast, which extends in an irregular band from central Pennsylvania down through eastern Tennessee and into northern Alabama. Cast is the technical name for the kind of terrain that forms when soluble rock like limestone is slowly eaten away by underground water over the course of millions of years.

What cast produces at the surface is a landscape that looks entirely ordinary from the outside. Rolling hills, wooded ridges, creeks running through narrow valleys. But what cast produces underneath the surface is something else entirely. It produces cave systems that can extend for hundreds of miles in a single connected network, punctuated by vertical shafts that open into caverns the size of cathedrals and threaded through with underground rivers that in some documented cases have never been fully mapped by any modern surveying effort.

The Ridgeback cast is one of the largest and least explored cast formations in North America. Most of it is on private land. Most of the private land owners either do not know what is under their property or in a small handful of documented cases know very well and prefer not to discuss it. The people who first settled Marlo Bend seem to have arrived sometime in the late 1790s though the exact date is disputed.

The dominant family was the Marlo themselves from whom the settlement took its name. There were also families named Perch, Culiver, and Austin, and a widow named Ruth Fay, who had come down from Pennsylvania with two grown sons. By the standards of Appalachian settlement in that era, this was a small and self-contained community.

They kept mostly to themselves. They traded a little through Zebulon Foss’s store at Danver’s Fork, mainly wax, honey, cured hides, and a peculiar dark salt that they seem to have been harvesting from somewhere inside the ridges. Though nobody outside the settlement ever saw the source, they did not attend church elsewhere.

They did not send their children to any outside school, and they did not accept visitors overnight. That last detail is one that appears again and again in the outside accounts. If you rode into Marlo Bend during the day, you would be received politely, given water for your horse, and sold whatever small goods you had come to buy.

But you would be gently and firmly encouraged to be back over the limestone shoulder and out of the bowl before the sun went down. One outside visitor whose account has survived is worth mentioning briefly because his description of the settlement gives us the most vivid firstirhand picture of daily life in Marlo Ben that we have.

His name was Reverend Amos Thood, and he was a Baptist itinerant preacher who passed through the region in the summer of 1847, and who, unlike the Methodist circuit riders who serviced the settlement regularly, had no prior connection to the community, and no reason to see it as anything other than one more remote hollow among the many hollows he visited that year.

Thood spent one afternoon in Marlo Bend. He was received courteously. He was fed a good midday meal at the Perch Cabin. He was offered a cup of cider that he described in his travel journal as “the finest small drink I have taken this side of the Susuana” and he was shown briefly the meeting house which he noted was tidy well swept and equipped with a pulpit Bible that appeared to have been printed in Philadelphia in the 1790s and that showed signs of regular use.

He also noted, and this is the passage from his journal, that Karin Halbastam would eventually track down and photocopy for her own files, that the settlement had an unusual quality of stillness about it that he could not entirely account for. He wrote:

“The folk here are kind, and their houses are in good order, but I cannot shake the sense that the settlement holds itself in a kind of listening posture, as if attending to a sound that I cannot hear.”

He was gently reminded as the afternoon wore on that he would want to be over the limestone shoulder before dark, and he was helped politely onto his horse and pointed toward the trail. He looked back once, as he was cresting the switchback, and saw that three of the adult residents were still standing in the yard of the meeting house, watching him go. They did not wave.

They simply watched. At first, the outside settlers who dealt with them assumed this was simple frontier caution. The ridges above Marlo Bend were known to have wolves and later panthers, and the trail out was genuinely difficult to navigate in the dark. But over time, it became clear that the rule was not really about danger from the outside.

It was about something else. Zebulon Foss in his ledger made a note in the margin next to an entry from 1843 that reads, and this is a direct quote from his ledger which is now preserved in a private collection in Wheeling, West Virginia:

“They do not want us to see who comes up.”

Just that one sentence in the margin next to a routine sale of nails and lamp oil. He never expanded on it in his ledger. But we know because his grandson wrote about it in a memoir published in 1921 that Foss believed until the day he died that the Marlo Ben settlers were sharing their valley with somebody else. Somebody who came up at night, somebody the outside world was not supposed to know about.

Now, for a long time, this was treated as the kind of eccentric old man story that gets attached to any isolated Appalachian community. Every hollow in that country has a ghost story or a witch story or a lost silver mine story. The Marlo Ben story in the version that survived into the 20th century was usually dismissed as another one of those.

But then in 1953, a graduate student at the University of Virginia named Karin Halbastam went looking through the Beckwith family papers as part of a thesis on rural Methodism in the antibbellum south. And what she found in those papers was IAS Beckwith’s original report from the morning of October 14th, 1861. the full report, 14 pages of dense handwritten script, including a sketch of what he saw when he went into the second cellar of the Marlo house.

And once you read that report, once you actually sit with what Beckwith described, the eccentric old man’s story stops sounding eccentric. It starts sounding like a warning that nobody outside the bowl was ever supposed to hear.

Elias Beckwith arrived at the mouth of the Marlo Ben Trail on the evening of October 13th, 1861 and spent the night in a leanto about a/4 mile up the switchback because it was already too dark to safely descend into the bowl. He was 34 years old at the time. He had ridden the Marlo Ben Circuit twice a year for the previous 6 years, and he knew the settlement well enough that most of the adults there would greet him by name. His purpose on that particular trip was to conduct a small baptism for a child born to the Culver family in early September and to collect a promised donation of tallow candles for the church at Danver’s Fork.

He had every reason to expect a quiet, ordinary morning. Instead, he rode into a settlement that had been abandoned in the middle of a night. The first thing he noticed as he came down the last stretch of the switchback and could see into the bowl was that no smoke was rising from any of the 11 chimneys.

This was unusual because the mornings in the ridge country were already cold by mid-occtober and every household would normally have had a breakfast fire going by that hour. The second thing he noticed was that the fields which should have had figures moving in them were empty. Not just of people, of animals as well.

No dogs, no wandering geese, nothing. And the third thing which he described in his report as the moment his stomach began to turn was that every single door on every single cabin was standing wide open. He rode down into the bowl and dismounted at the meeting house first because that was the natural gathering point and because the meeting house door was open too. He called out.

He got no answer. He went inside. The pews were empty. The pulpit Bible was open on the reading stand to the book of Isaiah, which was where it had been on his last visit. There was a single unlit candle on the pulpit. Nothing else. He came back out and started walking house to house.

The perch cabin, which was the closest to the meeting house, showed the same pattern. Door open, fire cold, but not long cold. Bread cooling on the table, which meant it had been baked that morning or the night before, but nobody had cut into it. Two wooden plates were set at the table. A knife was on one of the plates, a shawl was hanging on the back of one of the chairs.

Beckwith noted specifically that the shawl belonged to Mildrid Perch, a woman he had known for years, and that she was the kind of person who never left the house without it once the weather turned. He walked through every room. He looked in the loft, there was no one there. He repeated this process at the Ostend cabin, the FA cabin, the two Marlo cabins, and the Culver cabin.

In every single one, the same pattern. Doors open, fires cold or cool. Meals half prepared. Personal belongings, including things that no rural 19th century woman would ever leave behind willingly, sitting untouched on tables and beds. In the Culver cabin, he found the cradle he had come to bless. It was empty.

The blankets in it were disturbed, as if a small child had been lifted out of it quickly, but there was no sign of struggle. The child, whose name was Amos, was 7 weeks old. Beckwith went to the livestock pens next because his mind was starting to look for any rational explanation. If the settlement had been raided, the livestock would be gone.

If the settlement had been struck by disease, there would be bodies. If the settlement had been struck by fire, there would be ash. The livestock were all there. Every cow, every pig, every chicken, every horse, all of them fed, all of them watered, all of them calm. Somebody had done the morning chores. That was the detail that made Beckwith sit down on the edge of a fence rail and try to think.

Somebody or several somebody’s had gotten up early, tended to the animals, and then walked away from the settlement so completely that not one adult and not one child remained, and they had done it without waking a single dog. Because there were dogs in Marlo Bend, Beckwith knew this because he had scratched their ears on prior visits. He counted three dogs.

All of them still there. All of them alive. All of them lying in the yard between the cabins in a strange loose formation that he described in his report as seeming to face outward as if watching for something. None of the dogs would look at him. This was the detail he underlined in his report.

None of the dogs would look at him. He walked among them. He crouched down in front of one of them, an old brown mongrel that he knew had belonged to the widow Ruth Fay. He put his face in front of the dog’s face. The dog was breathing normally. The dog’s eyes were open and clear, but the dog was looking past him over his shoulder toward the ring of ridges above the bowl, as if there was something up there that required its full attention.

When Beckwith stood up and walked to the other side of the dog and crouched down again, the dog turned its head very slowly to keep looking at the same point on the ridge line. It never once in the 15 or 20 minutes that Beckwith spent examining the yard, focused its eyes on him.

He wrote later that he had never in his life felt more alone than he did in that moment, standing among three living dogs who could see him perfectly well, and had decided, for reasons of their own, that he was not worth acknowledging. It was while he was sitting on the fence rail that he saw the meeting house door from the inside for the first time.

He had walked through it earlier, but he had not thought to close it and look at the interior surface. Something about the angle of the morning light must have caught the carvings. He got up, walked back over, pulled the door partly shut, and stopped. The message was cut deep, deep enough that Beck with initially thought it must have been done with a wood chisel over the course of hours.

There were 42 individual characters arranged in seven rows of six. None of them corresponded to any alphabet he recognized. They were not Cherokee syllary, which he knew well enough to identify, because there had been a small population of eastern band Cherokee still living in that part of the mountains at the time.

They were not Greek. They were not Hebrew, which he could read as a Methodist minister trained in the biblical languages. They were not any variant of Latin or the runic alphabets he had seen in academic books. They were something else entirely. And the cuts, when he examined them closely, were not made with a chisel at all.

They were made with something narrower, something that had left a distinct three-lobed groove at the base of each stroke. He could not identify the tool that would produce a mark like that. He copied every character carefully into his report. He measured the depth of the cuts. He noted the direction of the wood grain. And then he walked back to the Marlo house, which was the largest cabin in the settlement and which belonged to the family the settlement had been named for because the front door of the Marlo house had been standing open like the rest. But there was one thing about the Marlo house that made it different, and that was the small square trap door set into the kitchen floor.

The trap door was open, too, and a lantern, still burning low on almost the last of its oil, was sitting next to it. Whoever had been the last person in that kitchen had opened the trap door and gone down.

Beckwith had been in the Marlo house before. He knew that the trapoor in the kitchen led down to a root cellar, which was the ordinary kind of cellar you would find in any Appalachian farmhouse of that era. Stone walls, a dirt floor, shelves along one side for jars of preserves and burlap sacks of dry goods, a cool space kept at a steady temperature by the earth around it, useful for storing food through the summer heat, and for keeping smoked meat through the winter.

He had gone down into it once, at least on a previous visit, when old man Marlo, whose given name was Silas, had brought up a jug of cider for a shared meal after a Sunday service. It was, in every respect that Beckith had ever noticed, an ordinary cellar, but when he picked up the lantern and started down the wooden ladder that morning, he noticed almost immediately that the cellar had been rearranged.

The shelves along the eastern wall had been pulled away from the stone. The dry goods sacks that had been on them were stacked in a neat pile in the center of the floor and behind where the shelves had been set into the stone of the wall was a second door. Beckwith described this second door in his report with the kind of precise detail you get from a man who is making sure that if nobody believes him at least the record will be exact.

The door was rectangular. It measured approximately 3 ft wide by 5 ft tall. It was made of a dark wood that was not oak, not pine, not chestnut, and not any of the other timbers native to that part of Appalachia. He could not identify the species. The wood had been fitted directly into a frame that appeared to have been carved out of the living limestone of the wall, which meant that whoever installed the door had done so before the cellar itself was finished.

The door had no visible hinges. It had no visible handle. It had no keyhole and no lock plate. There was a single symbol cut into the center of the door at about eye height. The symbol was one of the same 42 characters that Beckwith had copied from the meeting house door. When he held the lantern close to the wood, he saw that a very fine layer of pale dust had settled along the bottom edge of the door, and that the dust had been disturbed recently by something being drawn across it from the far side.

Something had come through this door within the last few hours. The door was standing open by about 4 in. Beckwith could see nothing through the gap except black. He held the lantern up. He moved the lantern from side to side. He tried at one point to angle the lantern so that its light would fall through the gap and illuminate whatever was on the other side.

The light did not seem to penetrate the gap in the way it should have. Beckwith noted this specifically in his report, and it is one of the details that has caused some of the more scientifically minded readers of his report over the years to argue that Beckwith must have been mistaken about what he was seeing, because light does not simply refuse to enter a space.

But Beckwith was very clear about it. The lantern was a good lantern. The oil was fresh. The wick was trimmed. The lantern was throwing a strong yellow light in every direction on the cellar side of the door, and through the 4-in gap, the light stopped as if it had run into a solid wall of dark water.

He could see the edge of the door frame on the far side faintly, just at the extreme edge of what his lantern could reach. Beyond that, nothing. There was also a smell coming through the gap. Beckwith described it as being like nothing he had ever smelled before, though he tried in his report to approximate it with a series of comparisons.

It was, he wrote, faintly like cold riverstone, faintly like the inside of an old beeswax candle, faintly like the air inside a deep well that has not been opened in many years. And underneath all of those, there was a fourth note that he could not describe at all, except to say that it was not unpleasant, and that it made him want very strongly to walk through the door and go down.

He did not, and this is important, he did not open the door further. He stood in front of it for what he estimated in his report was perhaps 3 or 4 minutes, holding the lantern up, listening, and trying to understand what he was looking at. And in those three or four minutes, twice he heard something on the far side of the door.

not footsteps, not voices. A soft, dry, repetitive sound that he compared in one of the more chilling passages of his entire report to the sound of somebody very slowly and very carefully unrolling a large sheet of parchment. It came from below, and it came from a considerable distance away.

And after the second time he heard it, he backed up the ladder, closed the trap door, and walked out of the Marlo house. He got on his horse. He rode back up the switchback. He did not stop. He did not look back. And when he reached Danver’s Fork 3 hours later, he went directly to Zebulun Foss’s store and told Foss exactly what he had seen.

Foss, according to his grandson’s memoir, did not seem surprised. Foss’s only reaction, according to the memoir, was to sit down heavily on a stool behind the counter, close his eyes, and say,

“So they finally called them all down.”

That was the sentence that would appear decades later in the margin of Foss’s private ledger as a kind of dated confirmation of a suspicion he had held for at least 18 years.

Now the natural question here and the question that Beckwith himself asked in the second half of his report is what exactly Marlo Bend had been doing all those years. Because you do not build a hidden door of foreign wood into the back wall of your root cellar by accident. You do not carve an unknown alphabet into your meeting house door on the last night you are ever going to be in your house by accident.

And you do not have three separate settlements worth of adults simply walk away from every material possession they own, including the babies in their cradles, unless somebody or something has convinced them that walking away is the only option they have. Beckwith understood this and in the second half of his report he began cautiously and carefully to reconstruct what he thought the settlement of Marlo Bend actually was.

His conclusion based on the note from Zebulon Foss based on his own six years of observation based on the character of the settlers he had known was that Marlo Bend had never really been a Christian frontier settlement in the ordinary sense. It had been a caretaker community, a very small, very quiet, very disciplined community whose real purpose generation after generation was to sit above a specific opening in the limestone and keep it managed, keep it fed, keep it acknowledged, and keep the outside world from noticing that there was anything down there to acknowledge.

The Christian trappings, the meeting house, the circuit rider visits, the Sunday services were, in Beckwith’s carefully worded phrasing, a kind of protective coloration, something that made the settlement look normal to anybody who visited during daylight hours. But the actual life of Marlo Bend, the actual reason those 47 people were living in that particular circular valley in the middle of nowhere, had almost nothing to do with any of it.

The actual life of Marlo Bend happened at night and it happened underground and it had been happening for a very long time before 1861. To understand how a caretaker community ends up in the ridges of western Appalachia in the first place, you have to go back further than 1861. You have to go back further than the late 1790s when the Marlo and the Perches and the Culver first arrived in the bowl.

You have to go back actually to a set of much older stories. Some of them Native American, some of them carried across the Atlantic by the earliest waves of Scots, Irish, and German settlement, and some of them older than either. Because the pattern of a small human settlement built directly on top of a limestone opening for the specific purpose of managing something that lives beneath the surface, that is not a pattern unique to Marlo Bend.

It shows up quietly in a handful of other places along the eastern ridges. And once you know what you are looking for, you can trace the same handful of families through several of them. The Marlo name, for example, appears in a Moravian church record from a settlement in what is now central Pennsylvania in 1732. That settlement called Austin Hook by its founders was abandoned in 1741 under circumstances that the surviving Moravian records describe only as, and this is the surviving Latin phrase from the Diosisan archive, a matter unfit for further inquiry.

The perch name appears in a colonial court record from western Virginia in 1768 in connection with a land dispute involving a small settlement called Kappla’s sink which was likewise abandoned within a decade and which sat directly on top of a documented limestone cave system. The culiva name appears in the passenger list of a ship called the Hanover Marie which arrived in Philadelphia in 1721 carrying a small congregation of religious separatists from the Palatinate region of what is now western Germany whose specific theological convictions were considered so unusual by the mainstream Protestant churches of the colonies that they were in the language of the period refused fellowship on arrival and directed westward to find land of their own.

What all of these threads point to when you pull them together is that the settlement of Marlo Bend was not founded in the late 1790s by pioneers who happened to stumble into a good valley. It was founded by descendants of a much older group who had been quietly moving west one generation at a time for it at least 3/4 of a century and who were looking for a very specific kind of place. a circular limestone bowl sheltered by ridges with a clean water source in the center and with an existing opening in the rock that led down into a cave system large enough to matter.

Once they found the bowl, they settled it. They built the 11 cabins in a rough ring around the meeting house. They dug the root cellar of the Marlo house directly on top of the primary opening. They fitted the second door into the wall of that cellar. And then for the next roughly 65 years, they lived a double life. During the day, they were a small, quiet Appalachian farming community.

At night, at least on certain nights, they went down or they let something come up and they kept records of what happened when they did. Before we get to the ledger, a word about Kurin Halbastam. because her role in this whole story is often understated in the summaries that get passed around and because without her the rest of what we know would still be sitting in a private family collection in Wheeling Unexamined, Karin Halba was 26 years old in the spring of 1953.

She had come to the University of Virginia after finishing her undergraduate work at Binmar where she had studied both religious history and anthropology and she had chosen the topic of rural Appalachian Methodism for her graduate thesis in part because she was tired of the fashionable topics of the day and in part because her grandfather Emmett had grown up in western Maryland and had taught her when she was a child to love the ridge country.

She was, by every account of every person who knew her personally, quiet, exacting, extremely patient with primary sources, and completely without any interest in the sensational. When she stumbled into the Beckwith report during a routine survey of Methodist minister papers in the university’s rare books collection, her initial reaction, according to her own field journal, was mild irritation.

She thought at first that the report must be a fabrication of some kind, either a hoax that Beckwith himself had produced for reasons of his own, or a later insertion into the family papers by a descendant with a taste for the Gothic. She spent almost 4 months verifying the paper, the ink, the handwriting, and the correspondence surrounding the report before she was willing to accept that the report was what it appeared to be, which was a firstirhand contemporaneous account of an event that mainstream Appalachian history had somehow completely lost track of.

Once she accepted that, she went back to Marlo Bend twice in the summer of 1954 to see what was left of the physical settlement. What she found 93 years after the disappearances was that the cabins had all collapsed or been dismantled. The meeting house had burned at some point in the 1870s, probably struck by lightning.

The orchard had reverted to wild forest. The stream still ran. The salt lick at the northern edge of the fields was still there, and the Marlo house foundation was still visible, including the stonelined pit that had been the root cellar. What she did not find, and what she noted with some frustration in her field journal, was any sign of the second door.

The stone wall behind the collapsed shelves had either been sealed up sometime after 1861, or had never actually existed the way Beckith described it, or had been removed entirely. She dug at the base of the wall for 2 days and found nothing but limestone. However, on the third day of her second visit, in a small overhang cave about half a mile up the western ridge, she found something else.

She found a ledger. It was wrapped in oiled leather and sealed inside a wooden box that had itself been wedged into a crack in the cave wall. The leather was in relatively good condition. The pages were fragile but readable. And what was on the pages over the course of what she estimated to be seven decades of entries was a running record of every single time somebody from Marlo Bend had opened the second door and either gone down or received someone who came up.

The first entry in the ledger was dated the 11th of March 1798. The last entry was dated the 12th of October 1861, 2 days before Elias Beckwith rode into the bowl and found it empty. The ledger contained, among other things, a running population count, not of the settlers, of the ones below. And the count in the final entry was, in translation from the archaic English shorthand the writer used:

“We do not know how many any longer. We have lost the count. They are more than we thought, and they say they are ready.”

That is the last thing anybody in Marlo Bend ever wrote down. Karen Halbastam took the ledger back to Charlottesville. She had it examined by a specialist in early American manuscripts at the University of Virginia Library who confirmed that the paper, the ink, the binding thread, and the shorthand style were all consistent with the period the entries claimed to cover.

The shorthand itself was a variant of what is known as shorthand, an 18th century English system that was popular among Quakers and other religious dissenters in the early American colonies. It took two graduate students and a professor of old English almost 8 months to produce a full transcription. When the transcription was complete, and when Halam sat down to read it in order, what she had in her hands was one of the most disturbing documents in the private history of Appalachian settlement.

The Ledger recorded in careful chronological order every meeting between the surface community of Marlo Bend and what the Ledger writers across the seven decades and multiple different handwritings consistently referred to as the below folk, not demons, not spirits, not devils, not any of the usual language of 19th century Appalachian folk belief, just the below folk.

as if the writers understood them to be a specific real populated group of beings whose existence was so ordinary from the perspective of the settlement that no theological framing was required. The first few entries in the ledger from 1798 through about 1805 are largely administrative. They record the initial finding of the opening in the limestone which the writers describe as being already partially widened by earlier human work of some kind.

Though they do not speculate on who did the earlier widening, they record the fitting of the second door which was done according to the ledger using timber that was brought up from below rather than cut on the surface. This is the first mention of the strange dark wood that Beckwith would later see in the cellar. They record the establishment of what the writers called the terms, which was a set of standing agreements between the surface community and the below folk governing the frequency, purpose, and conditions of contact.

The terms, as the ledger described them, were simple. The below folk would not come to the surface during daylight hours under any circumstances. The surface community would not descend below the second door except on specific agreed dates. Contact would happen only at the door itself, only after dark, only on the 1st and 15th of each month, according to the surface calendar, and only for specific purposes, which were mostly the exchange of certain goods that each community could produce more easily than the other.

The below folk provided the dark salt that the settlement traded through Foss’s store. They also provided a kind of pale waxy substance that the surface community used for candles and that burned with almost no smoke. In exchange, the surface community provided grain, dried fruit, honey, and most importantly, iron. The below folk, according to the ledger, did not work iron themselves, and had a persistent need for iron implements of specific dimensions, particularly small blades and long, thin nails.

There is nothing in the early ledger entries that suggests the surface community was afraid of the below folk. The tone throughout the first three decades of entries is businesslike, occasionally cordial, sometimes even affectionate. Individual below folk are named in the ledger by what appear to be phonetic renderings of their spoken names.

The names are short, two syllables, usually names like Vessin, Kell, Haroth, and Pth. The ledger records births, deaths, and personal news among the named below folk in the same tone that a small human community might use to record the same events among its neighbors in a nearby village.

There is one entry from the winter of 1812, for example, in which a ledger writer whose handwriting Halbastam’s team identified as belonging to a woman named Prudence Ostend records that a below folk contact named Vessin had lost a mother that month, and that Prudence and two other surface community members had gathered a small selection of dried herbs and a single beeswax candle, and had left the bundle at the second door as a morning gift.

The following meeting on the 15th of that same month, Vessin brought up a folded square of the pale waxy cloth as a return gift, along with a spoken message of thanks that Prudence took the trouble to transcribe phonetically in the ledger. There are a dozen or so entries of this same character scattered through the early decades.

small acts of mutual acknowledgement, recognitions of grief, the kinds of small gestures that two neighboring communities anywhere in the world use to signal to each other that they see each other as real. Reading those entries is what makes the later entries so hard to reconcile. Because the community that was capable of that kind of small kindness in 1812 is the same community that would find itself 49 years later walking down a ladder into the dark together.

The physical descriptions of the below folk in the ledger, which appear only occasionally and always in a matter of fact tone, are perhaps the most difficult part of the whole document to sit with. They are described as being roughly human in overall shape, though shorter than the average adult surface person, generally between 4t and 4 1/2 ft tall.

They are described as being extremely pale, almost white, with skin that had a slight translucent quality, especially around the hands and the face. Their eyes are described as being unusually large in proportion to the rest of the head and dark with a reflective quality similar to the eyes of certain nocturnal mammals.

They are described as being covered from neck to ankle in a garment made of the same waxy pale substance from which they made their candles, which the ledger writers understood to be something they produced themselves from a source that was never explained. They spoke a language of their own which several of the surface community members learned well enough over the decades to conduct trade in.

They also learned to speak and eventually to read English. By the 1830s, according to the ledger, at least three of the named below folk could read passages from a printed English Bible with reasonable fluency. There is one entry from May of 1837 that describes a specific evening at the second door in which a below folk woman named Pth brought up a very young child, an infant of her own, and held it up to the door so that the surface community members present could see it.

The ledger writer, whose handwriting suggests it was probably Silas Marlo’s grandmother, records that the child had all the sweetness of any of ours at that age, though the eyes were already the great dark eyes of her mother. She records that she and Pth spoke for almost an hour about the difficulties of raising infants in the winter months.

She records that when Pth finally took the child back down, the ledger writer felt a great and unexplained sadness, as if I had lost a sister I had only just met. This is what the ledger is like for almost 50 years. Trade, birth notices, small acts of neighborliness, and the occasional strange gift.

It is not the record of a hostile relationship. It is the record of two very different communities that had learned over the course of generations to live carefully alongside each other in the same square mile of Appalachian Ridge country. And that is what makes what happens in the final 10 years of the ledger so difficult to read because in the early 1850s the tone of the entries begins to change.

Something is happening below. something the surface community does not fully understand and something the below folk themselves are increasingly reluctant to explain. The first entry that Halba and her transcription team flagged as clearly different in tone was dated the 22nd of March 1851. It was written by a man named Josiah Culiver who was at that point the informal head of the surface community.

The entry describes a routine trade meeting at the second door at which Josiah expected to speak with a below folk contact named Har who he had known for at least 15 years. Haroth did not appear. Instead, a below folk that Josiah did not recognize came to the door. This new individual was, in Josiah’s phrasing, taller than the others by perhaps half a foot, thinner in the face, with eyes that were noticeably darker even by the standards of the below folk.

He spoke English with no accent. He introduced himself only as a speaker for the others and he refused to give a personal name. The speaker told Josiah that:

“Har had gone deeper”

and would not be coming to the door again. He told Josiah that from that night forward all communication between the surface community and the below folk would be conducted through him or through one of two other speakers whose names he also did not give.

He told Josiah that the terms of trade would continue, but that certain adjustments would be required. And then he made a request that Josiah recorded in the ledger with visibly shaking handwriting because the ink of that particular passage runs uneven across the page in a way that the transcription team specifically noted.

The request was for a child. Not a specific child, not a named child, just a healthy human infant of either sex, ideally under 6 months of age, to be delivered to the second door on a night of the surface community’s choosing within the next full calendar year. The speaker did not explain why. He did not offer anything in exchange.

He simply said that this request was now part of the terms and that if it was not met, the trade relationship would end. Josiah refused, of course. He refused immediately without needing to consult the rest of the community. He told the speaker that no infant would be delivered to the door under any circumstances.

He told the speaker that if this request was the new condition of trade, then the trade relationship would in fact have to end. The speaker did not argue. He simply said,

“We will speak again on the first.”

And stepped back into the dark. Josiah closed the second door. He climbed the ladder.

He went upstairs, and according to a later note in the same ledger, he did not sleep that night. He sat at the kitchen table of his own cabin, which was the Culver cabin at the eastern edge of the settlement, with a loaded shotgun across his knees, watching the door. His wife, whose name was Mary Ellen Culliver, and who was pregnant at the time with what would be their fifth child, sat up with him.

Neither of them spoke much for most of the night. But at some point in the small hours of the morning, Josiah told Mary Ellen that whatever else happened, no child born to any household in Marlo Bend would ever be handed to anything that came up through that door, and that if the day ever came when the community was faced with a choice between keeping the door managed and protecting its own children, the door would go unmanaged, and the community would take the consequences of that decision on itself.

Mary Ellen agreed. She wrote out that agreement in her own hand on a small piece of paper that she folded and kept in the family bible and that piece of paper remarkably survived the abandonment and eventually made its way into Corin Halba’s field collection more than 90 years later. It reads in full:

“No child of ours not ever not for any reason so help us God.”

It is signed by both of them in the same ink. The next entry on the 1st of April 1851 records the speaker returning to the door and without preamble informing Josiah that the request had been reconsidered and withdrawn. He offered no explanation for the reversal. He proceeded to conduct the ordinary trade for that date. Nails, small blades, dried apples in exchange for the dark salt and the waxy candle material. He was polite.

He was efficient. He asked after the health of specific named members of the surface community by name, and when the trade was complete, he thanked Josiah and stepped back into the dark again. Josiah, in his ledger entry, wrote that the whole meeting had left him feeling more disturbed than the request itself had, because it felt, in his exact words, as if a thing that had been decided was being merely postponed.

Over the following four years, the entries in the ledger record a slow but steady change in the character of the below folk community. Individual named below folk who had been familiar for decades stopped appearing at the door. New below folk, always taller and thinner and darker eyed than the older ones, appeared in their place.

The waxy candle material started to arrive in smaller quantities and with a slightly different smell when it burned. The dark salt started to arrive in larger quantities than the surface community had asked for. Requests began to arrive for iron implements of unusual and specific shapes, some of them clearly not tools in any recognizable sense.

There is one entry from October of 1853 that records the surface community delivering a set of 37 iron rings of precisely graduated sizes. the largest about the diameter of a dinner plate and the smallest about the diameter of a coin. The surface community was not told what the rings were for.

By 1856, the entries in the ledger have taken on a tone of increasing alarm. Josiah Culliva died of natural causes in the winter of that year. And the ledger passes into the handwriting of a woman named Anna Marlo, who was Silas Marlo’s daughter, and who had, according to her own account, been present at the door on the night the child was requested.

Anna’s entries are shorter than Josiah’s and less business-like, and she is much more willing to record her private impressions. In an entry from June of 1857, she writes:

“They are not the ones we knew. Something has come up from further down, and it is standing in their places and using their doorways. The old ones would speak to us of their children. These new ones will not speak of anything except the trade and one other matter which I will not write here.”

She does not say what the other matter is. It is one of many things Anna Marlo would carry to her grave. Anna’s entries continue in this uneasy vein for another 3 and 1/2 years. The trade continues.

The meetings at the door continue on the 1st and the 15th of each month. But there is a growing sense in her writing that the surface community has become, without ever quite agreeing to it, a party to something they did not sign up for. The iron requests continue. The rings, long thin nails by the hund. In the winter of 1859, a request arrives for a full set of surgeons tools of the kind that were then being manufactured in Baltimore and Philadelphia for use on Union Army Medical Corps.

The surface community sourced them at considerable expense through Foss’s store and delivered them to the door in February of 1860. They were not told what the tools were for. And then in the spring of 1861, the entries in the ledger stop recording the ordinary trade at all and start recording something else. They start recording a countdown.

The first countdown entry is dated the 4th of April 1861 and it is written in Anamaro’s hand. It reads in full:

“They say 212 nights.”

That is the entire entry for that date. The next entry 4 days later on the 8th of April reads:

“208. They will not tell us what happens at zero.”

And from that point forward, every single entry in the ledger for the next 6 months carries a number at the top of the page, and the numbers count steadily down. 203, 199, 184, 171, 160, and so on. The ordinary trade continued through most of the countdown period, though at reduced volume and with an increasing sense of ceremony that Anna records in the ledger with a certain resignation.

The below folk who came to the door during this period were formal, polite, and completely unwilling to discuss what the countdown was for. Anna and the other surface community members asked directly more than once. Each time they asked, the speaker would respond with some variation of the same phrase, which Anna eventually stopped recording verbatim and started noting only as the usual answer.

The usual answer based on the two full transcriptions of it that do appear in the ledger was:

“We cannot tell you and you would not wish us to.”

By July of 1861, the countdown was at approximately 100 nights. And it was at this point that Silas Marlo, who was by then in his late 70s and physically frail, but still the elder patriarch of the settlement, made a decision that Anna records with obvious pride in the ledger.

He decided to send for outside help, not the church, not the local militia, not anybody who might have wanted to interfere with the settlement’s internal affairs. He sent through a very careful and securitous chain of trusted contacts a request to a man in Baltimore named Jonas Akaman who was known within a certain very small network of American religious denters as somebody who had made a lifelong study of what he called in his own private correspondents the older neighbors.

Akaman was not a minister. He was not a folklorist. He was in his day job a moderately successful hardware wholesaler. But in his private life, he had been quietly collecting accounts of encounters like the ones at Marlo Bend for almost 40 years, and he had built up a small but detailed working knowledge of what he believed these encounters actually were.

A word here about Jonas Akerman because he is going to come up again and because his background matters to what he saw. Akaman had been born in 189 to a family of Pennsylvania Dutch Anabaptists who had a long tradition of theological independence and an even longer tradition of taking very seriously the kinds of stories that mainstream American Protestantism had spent the previous century trying to explain away.

He had lost a younger brother when he was 14 years old in what his family had always described in private as an incident involving a hollow behind their farmhouse and a set of small footprints that led up out of the hollow and then simply stopped in the middle of a snowy field with no return trail.

His brother had been 9 years old at the time. Aan had spent more or less the rest of his life trying to understand what had happened to his brother. By the time Silas Marlo’s request reached him in the summer of 1861, he had accumulated a private archive of roughly 240 separate accounts of similar events from across the eastern United States and parts of the upper Midwest.

And he had developed a working theory of what he believed the older neighbors actually were. His theory, which he never published, and which survives only in fragments in his private letters, was that there were at least two distinct populations of them, that the two populations did not appear to be on good terms with each other, and that most of the historical trouble on the surface had been caused by contact with the deeper of the two.

Akaman arrived at Marlo Bend on the 9th of August, 1861, having traveled by rail as far as western Maryland and then on horseback through the ridges. He was 52 years old, physically compact and famously calm. He spent four full days in the settlement before he asked to be shown the second door. Anna records that he did not go through the door.

He examined it from the cellar side for about 2 hours by lantern light. He copied the symbol on the door face. He examined the wood. He examined the dust along the base. And when he came back up into the kitchen, he sat down at the Marlo family table, poured himself a cup of coffee, and told Silas, Marlo, and Anna the following, which Anna recorded in the ledger word for word because she understood correctly that it was the most important sentence in the entire document.

He said:

“The ones you have been trading with for 60 years are not the ones you are trading with now. The ones you have been trading with for 60 years are all dead. The ones you are trading with now came up from a great deal further down and they killed the older ones one at a time over the course of about 18 years and they are now using the older ones door because it is the only door on this continent that is still open to the surface. They are counting down to something and I cannot tell you what because I do not know. What I can tell you is that whatever they are counting down to, they cannot do it without the surface community’s cooperation. And the moment they no longer need your cooperation, they will not need you either.”

He advised in the strongest possible terms that the entire settlement should leave, that they should pack whatever they could carry, walk out over the limestone shoulder, and never come back.

He said he would personally arrange lodging for all 47 of them in Baltimore or Philadelphia at his own expense. He said the countdown was, in his judgment, approximately 60 nights out from whatever the terminal event was going to be, and that 60 nights was more than enough time to evacuate the bowl. Silus Marlo refused. He refused politely.

He thanked Akaman for his advice and for his generosity and for the great personal effort he had made in traveling to Marlo Bend at all, but he refused. His reasoning, as Anna recorded it in the ledger, was that the surface community of Marlo Bend had been established for a specific purpose, and that purpose was to keep the door managed.

If the surface community abandoned the door, and if what Akaman was saying about the current occupants below was true, then whatever was counting down to zero would count down to zero anyway, and it would happen without anybody at the door to witness it or to warn the outside world about what had happened, Silas said. And Anna records this with what appears to be genuine emotional weight.

“We did not come here to run.”

Aan stayed for three more days. He tried to persuade Silas privately and then Anna privately and then the heads of each of the other four families. None of them would leave. On the morning of the 15th of August, he rode out of the bowl up the switchback and back down the trail to Danver’s Fork.

He never saw any of them again. However, his private notes from that visit, which were preserved in the archives of a small religious historical society in Pennsylvania, contain one final detail that neither Anna’s ledger nor Beckwith’s later report ever recorded. According to Aceman’s notes, when he was examining the second door on the second day of his visit, he had heard something on the other side of it, something moving, something that was, in his own careful phrasing, breathing in a rhythm that was not the rhythm of any lungbearing creature he had ever encountered.

The 42 characters carved into the interior surface of the meeting house door on the last night of Marlo Bend have never been fully translated. Elias Beckwith’s careful copy of them made in the field on the morning of October 14th, 1861, has been examined by at least a dozen serious researchers over the past century and a half.

The Halba transcription team ran them past specialists in every ancient and modern script they could find contacts for. The characters do not match Sumerian Cunia form, though a very small number of individual characters bear a passing resemblance to certain protoelelomite signs from the third millennium before the common era. They do not match Ogum.

They do not match younger foothark or any of the Germanic runic traditions. They do not match any known Semitic alphabet. They do not match linear A or linear B. They do not match any of the Native American writing systems developed after European contact. What they do share in a way that at least three different independent examiners have noted is a certain structural relationship with a very small set of symbols that appear on a handful of small pieces of worked stone recovered from cave sites in the Ozarks in the Cumberland Plateau and in one cave in northern Alabama.

All of which have been dated by conventional archaeological methods to periods well before the arrival of any European or in most cases any Native American population in the area. The mainstream archaeological interpretation of these stone pieces is that they are either forgeries or natural markings that early amateur excavators misidentified as writing.

That interpretation may or may not be correct. What is true and what nobody in the mainstream has been able to explain is why 42 characters carved into a 19th century Methodist meeting house door in western Appalachia by an unknown hand in the middle of a single night should share any structural relationship with a set of alleged natural markings on cavestones scattered across the American southeast.

The characters themselves, as Beckwith copied them, are made up of straight lines and slight curves. Each character occupies roughly the same amount of vertical space as an English capital letter. Most characters have between three and six individual strokes. Several characters repeat within the message. The most frequently repeated character, which occurs 11 times in the 42 character message, is a simple three-stroke figure that resembles an inverted capital Y with an additional horizontal bar across the top.

That character was independently identified by two of the Halberam team’s consultants as bearing a strong resemblance to a symbol that appears on the largest of the alleged Cumberland Plateau cavestones, where it also occurs repeatedly and where it has been tentatively interpreted. Though nobody is confident about this as a name or a title, not a common noun, not a verb, a name.

The Cumberland Plateau Cave Stone in question for the record is currently held in a small regional museum in eastern Tennessee where it has been on display in a glass case in a back room since the 1930s. It was recovered from a limestone cavern about 12 mi from the town of Sparta by a farmer named William Ostend who was searching for a lost calf in the summer of 1922.

The farmer notably was a distant descendant of the same Ostend family that had been one of the founding families of Marlo Bend and had inherited from an aunt a handful of oral traditions about the Marlo Bend settlement that he was aware were considered by the outside world to be tall tales. When he found the stone in the cavern and saw the characters cut into it, he did not tell the outside world at first.

He took the stone home, wrapped it in oiled cloth, and kept it in a locked chest in his attic for almost 15 years before he finally donated it to the museum, and then only under conditions that specified that the stone was never to be moved from its display case and never to be photographed for publication. Those conditions were honored by the museum until 1956 when a member of the Halba research team was granted a private viewing and permitted to make a careful hand drawing.

That hand drawing sits in Karin Halbastam’s field notes to this day and the repeating character on the Sparta Stone and the 11 times character on the Marlo Ben meetinghouse door are when placed side by side indistinguishable to the human eye. If that tentative interpretation is correct, then the message on the meetinghouse door contains a name or a title repeated 11 times.

11, which is exactly the number of cabins in Marlo Bend, 11 households. And the message was carved from inside the meeting house on the last night that any of the 47 residents were ever seen alive. This is the kind of detail that you either dismiss as coincidence or you sit with for a long time. Halbaam sat with it. Akaman before his death in 1883 sat with it and the small handful of contemporary researchers who have spent any real time with the Beckwith report have all in one way or another sat with it.

The best guess and it is only a guess is that the message on the door was not a warning to the outside world. It was a formal document. It was the surface community in the final hours of their lives above ground, listing each household by whatever name or title the below folk used for them and marking that householders, in a phrase that Aceman used in his private notes about the message released from the terms.

that is each of the 11 households was being released from the 65-year-old standing agreement between the surface community and the older below folk because that agreement had been broken from below and no longer bound anybody. The message on the door was in this reading the settlement’s final legal act, its dissolution notice, written in a script that only the ones below would ever be able to read, which raises the question of what the surface community expected to happen after they wrote it, because a dissolution notice implies that there is no further relationship, and no further relationship implies that whatever came next was not going to be a trade meeting at the second door. It was going to be something else.

We know from Beckwith’s report that all 47 residents left the surface between roughly the last daylight of October 13th and the first daylight of October 14th. We know they left through the second door because the trap door was open. The lantern was still burning next to it, and the pale dust at the base of the door had been disturbed by many small feet passing through the gap. We know from Akaman’s private notes that on the specific night of October 13th, according to the countdown that had been running in Anamaro’s ledger since April, the count reached zero.

We do not know whether the 47 residents walked down the ladder of their own free will. We do not know whether they were called, whether they were compelled, or whether they simply decided collectively in the final hours that going down was preferable to whatever was going to come up if they did not. What we know is that they went and what we know is that nobody who followed the trail down after that night ever came back up to tell anybody what they found.

The people who did try to follow the trail down and there were three separate documented attempts between 1862 and 1912 all failed in ways that are worth briefly noting because they tell us something about what the second door actually was. The first attempt was made in April of 1862 by a party of six armed men organized by Jonas Akaman himself.

Akaman had spent the winter after the disappearance corresponding with Elias Beckwith and with Zebulun Foss, and he had concluded that some kind of formal investigation of the second door was owed to the memory of the 47 people who had gone through it. The party arrived at Marlo Bend in the second week of April, made camp in the meeting house, and descended into the Marlo House cellar on the morning of April 14th.

The second door was closed, but not sealed. It opened outward when they pulled on it, revealing a narrow passage cut through the limestone that sloped downward at an angle of approximately 30°. They followed the passage for what Akaman later estimated in his notes to be about 400 yd. At that point they came to a natural chamber roughly the size of a small barn in the middle of which sat what Acean described as a table of stone perfectly round perhaps 8 ft across its surface worn smooth by long use.

There was nothing on the table. There was no one in the chamber. There were three separate passages leading out of the chamber, each in a different direction, each descending further into the rock. Aan did not follow any of them. He and his party turned around and went back up. He wrote in his notes that on the way back up the passage, at approximately the halfway point, all six of them had simultaneously experienced what he called a compulsion to sit down and to remain in that place until called for.

It took what he estimated was a full 10 minutes of collective effort to overcome the compulsion and continue climbing. The second attempt was made in the summer of 1890 by a small spelological society from the University of Pennsylvania whose members had heard rumors of the Marlo Bend cave system through unrelated channels and who had no knowledge of what had happened in 1861.

Three of the four members of their surveying party entered the second door on the morning of July 12th. Only one of them came back out. He walked out of the Marlo house cellar at approximately noon the next day, was found wandering in the fields by a local hunter, and was unable to answer any questions about where the other three members of his party had gone.

He remained unable to answer questions about it for the remaining 41 years of his life, during which he lived in a small private sanatorium in Philadelphia at the university’s expense and rarely spoke to anyone. The other three members of the party were never found. The Marlo Bend Valley was not entered again by any organized party for the next 22 years.

The third attempt in 1912 was made by a single man. His name was EMTT Halbastam. He was Karin Halbastam’s grandfather. He was 31 years old at the time and he had learned about Marlo Bend from an elderly Pennsylvania woman who had been the last living person to have known Jonas Akaman personally. Emmett was a mining engineer by profession, and he approached the second door with a professional interest in the geology of the cave system rather than any interest in the folklore.

He entered the door alone on the morning of September 5th, 1912, carrying two carbide lamps, 400 ft of rope, a compass, a notebook, and a cult revolver. He came back out on the evening of September 6th, 37 hours later, having lost both lamps and his notebook, with the revolver still in his belt and every chamber of the revolver still loaded.

He was pale and shaking and unable to walk without help. But he was alive, and after he had rested for several days at a boarding house in Danver’s Fork, he was able to speak coherently about what he had seen. What he said in a written statement he made to his own family a week later and which Karin Halbastam would eventually inherit was that the passages below the second door extended for miles that they were unquestionably artificial in origin, that they were still inhabited, that the beings who inhabited them were aware of him from the moment he entered the door, and that they had allowed him to come back up only because they had decided, for reasons he did not understand, that his account of what was down there might be useful to them.

EMTT Halbastam refused for the rest of his life to describe in specific detail anything he had actually seen below the second door. When his granddaughter Karin first asked him about it when she was a girl of 11 or 12 visiting his farm in western Maryland, he had told her only that some things did not want to be described and that he had made a promise to the ones below that he intended to keep.

When she asked him again years later when she was a graduate student and had shown him the Beckwith report and was trying to piece together what had happened at Marlo Bend, he had sat very quietly for a long time and then said something she wrote down in her field journal that same evening because she was afraid she would misremember it. He said, and this is her exact transcription:

“They let me come back so that a certain kind of person sooner or later would know that they are still down there and that they are waiting. They did not tell me what they are waiting for, but I have thought about it every day for 40 years, and I believe now that they are waiting for us to make the mistake of forgetting that they exist.”

He would say only, when pressed further, that the passages continued to descend for as far as he had followed them. That at the bottom of everything he had seen, the passages open out into what he called a place large enough to hold a city, and that a city was in fact what appeared to be down there. Not a natural formation, not a cave, a city built of the pale waxy material that had once been traded up through the second door in the form of candles, lit from below by a source of light he could not identify.

inhabited by a population that he estimated to be, and this is the phrase he used with his family and that Karin recorded in her own field notes, at least in the low millions. EMTT Halbastam was not a man given to exaggeration. He had spent his working life estimating volumes of ore under mountains, and he understood the difference between hundreds and thousands and millions.

When he said millions, he meant millions. And when he said the population below the second door of a single abandoned Appalachian farmhouse was in the low millions, he was making a claim that either has to be dismissed as the raving of a traumatized man, or it has to be taken as a data point that reshapes everything we think we know about who else has been living on this continent for however long the passages have been down there.

Corin Halbastam took him at his word. That is why she kept looking. Karin Halbaam spent the remaining 23 years of her life trying to place Marlo Bend in a larger context. She did not publish her findings. The University of Virginia would not let her. Her thesis adviser, who had been sympathetic to the early work she did on the Beckwith report, quietly withdrew his support once she began linking the Marlo Bend material to the Ozark cave and to a series of what she called sister settlements that she had begun to identify in other parts of the Eastern Ridge country.

She lost her graduate funding in 1957. She continued the research on her own, working as a substitute teacher and later as a private tutor. And she died of pneumonia in a small apartment in Charlottesville in 1976, leaving behind three metal filing cabinets of unpublished field notes.

Those field notes were inherited by her nephew, who did not know what to do with them, and who eventually donated them to a small folklore archive in West Virginia in the late 1990s. They sat largely unread in that archive for about 20 years. When they were finally examined by a serious researcher in the 2010s, what emerged from them was a map, not a formal map, a working map that Karin had assembled over decades, marked in pencil on a large sheet of paper that she had folded into eighths and kept in the back of the second filing cabinet.

The map showed the eastern half of the United States from central Pennsylvania down through Georgia. And it had 31 small circles drawn on it, each with a date and a short annotation. Each circle represented a documented settlement similar in size and layout to Marlo Bend that had either been abandoned under mysterious circumstances between the late 1700s and the middle 1920s or that was still occupied but that Karin had reason to believe was operating on the same caretaker model.

Marlo Bend was one of the 31. It was the 16th to be abandoned. 15 others according to Karin’s map had gone before it. 15 more had followed, and an unknown number of the 31 may still be there, going about their careful, quiet daytime lives, keeping their doors managed, and never being back over their limestone shoulders after dark.

The map is the reason this story matters. Now, because if Karen was right, and if her map is even approximately accurate, then what happened at Marlo Bend in October of 1861 was not a one-time event. It was one of at least 16 similar events spread across almost 150 years in which a small human community that had been living in careful managed contact with something below the surface either broke that contact or was consumed by it.

And the number of those events that we know about is almost certainly smaller than the number that actually occurred because most of these settlements were by design so small and so quiet that when they disappeared, nobody outside the ridge country noticed. Marlo Bend is documented only because Elias Beckwith happened to ride in on the specific morning he did and because he happened to be the kind of man who wrote down what he saw.

The other 15 we know about are documented only because of decades of quiet detective work by Karin Halbastam and a handful of others working in the same tradition. The ones we do not know about are by the nature of the case the ones we do not know about. Two of the other 16 abandoned sister settlements are worth naming here because they illustrate the pattern and because their stories in miniature echo the shape of what happened at Marlo Bend closely enough that the coincidence stops being possible.

The first is a settlement that appears on Karin’s map as Blackwater Rise in what is now western North Carolina, which was abandoned sometime in the winter of 1843. The details of the Blackwater Rise abandonment are less well documented than the Marlo Bend abandonment because there was no equivalent of Elias Beckwith to ride in the next morning and take notes.

What we know is that a traveling Cooper who passed through the valley in the spring of 1844 found the settlement empty, all the cabin doors standing open, the livestock still in their pens and calm, and a series of characters in an unknown script carved into the interior surface of the settlement’s small church door. The Cooper was not a literate man and did not think to copy the characters, but he did report the abandonment to the county authorities in Asheville, who dispatched a small party to investigate.

The party found what the Cooper had described, took no notes, and closed the file. The settlement was not entered again for another 60 years. The second is a settlement that appears on the map as Del Hollow in what is now northern Georgia, which was abandoned in the summer of 1906. Delph Hollow is the most recent of the 16 documented abandonments and it is the one for which we have the most substantial secondary documentation because by 1906 there were newspapers in the surrounding counties and the abandonment was briefly noted in the local press before as with all of the others.

The story quietly disappeared from public discussion within a few weeks. The Del Hollow abandonment involved 31 residents. Their doors were standing open. Their livestock were fed. And on the interior surface of their small clapboard chapel, according to a single surviving photograph that Karin tracked down in the private collection of a retired newspaper editor in Rome, Georgia, were carved 31 characters in seven rows, arranged in exactly the same way as the 42 characters on the Marlo Bend meetinghouse door.

The photograph is grainy. The characters are hard to make out in detail, but the pattern is unmistakable. If you live in ridge country in the eastern United States and there is a valley near you that has a stream running through the center of it and a limestone shoulder on the trail in and the road just ends without a good reason at what looks like it used to be a settlement.

You might be looking at one of them and if you are and if the settlement is still occupied, you will notice that the people who live there are perfectly friendly during the day and quietly firm about you being gone before sunset. That is the tell. That has always been the tell. The story of Marlo Bend is not the story of a haunting.

It is not the story of a curse. It is the story of a small group of people who found something under the ground in western Appalachia in the late 1790s decided that the responsible thing to do was to sit on top of it and manage it quietly for as long as they could and then over the course of the middle 19th century lost control of what they were managing.

It is the story of a door made of a wood nobody could identify and a language nobody could read and a countdown that reached zero on a specific night in October when 47 people walked down a ladder together and never came back up. And it is the story of a small unfinished map drawn in pencil tucked into the back of a filing cabinet that suggests there are at least 30 more places like Marlo Bend still out there.

Some of them still occupied. Some of them still keeping their doors carefully managed. And all of them counting on the outside world to keep not noticing. IAS Beckwith noticed. Karen Halbastam noticed. Now you have noticed too. What you do with that is up to you.

Next time we descend, we go into a valley in the Ozarks where the last resident wrote one sentence in the dirt of her kitchen floor before she left. That sentence is the reason we are going.
