The voice came from the tree line about a hundred yards off, and it spoke one word only. Callaway. Just that. The sound of it stopped him cold in the act of unsaddling his mule, and he stood there in the failing light with one hand still on the cinch, because the voice was not his own.

It was Wendelin’s voice. The same slight accent, the same way of pulling on the second syllable, the same hoarse undertone that came from years of tobacco and mountain air. Wendelin Brusk had built this line cabin with him two years earlier, and sometimes Wendelin rode out from Pinedale when supplies needed bringing up, so Callaway called back. There was no answer.

He waited. He listened. Then he heard it again. Callaway.

From a different spot in the trees, maybe forty feet to the left of where the first call had come from. Callaway Renfield was not a man who spooked easily. He had been alone in the Wind River Range for seven years by the autumn of 1887, a tall, lean trapper of twenty-six with pale gray eyes the color of river ice in November and a long scar across the back of his left hand from a beaver trap that had snapped wrong when he was twenty-three. He had killed two grizzlies and been treed by a third.

He had pulled a wolf out of one of his own traps with his bare hands when his rifle jammed. But the second call put his hair up, because the voice had sounded identical to the first, and the place it came from was a place a grown man could not have walked to in the time between the two calls. Not without footsteps. Not without movement.

He pulled his rifle off the saddle, walked into the cabin, barred the door, and did not go outside again until full daylight. In the morning he found his own boot prints, his mule’s tracks, and nothing else. No human footprints. No horse tracks.

Nothing. That night he wrote in his journal that whatever had spoken his name had not approached the cabin on legs the way he understood legs to work. Nine days later he was higher up, near timberline, checking a marten set, when he heard a woman crying. The sound came from below him, from a thicket of alder along a small frozen seep.

It was a young woman sobbing the way a person sobs when she has given up, broken and exhausted and pleading without words. Callaway had not seen another human being in eleven days. There were no settlements within thirty miles. The nearest Shoshone winter camp was two days’ ride to the south, and they would not have had a young woman wandering alone at six thousand feet in late October.

Every instinct he had as a trapper told him to leave, but he was not the kind of man who could walk away from a woman crying in the cold, so he started down toward the seep. He got within sixty feet of the alder before he stopped, because the crying had changed. It had not gotten louder or softer. It had simply changed.

The pitch had shifted. The rhythm of the sobs had become too regular, too even. He wrote that it had stopped sounding like a woman and started sounding like something practicing what a woman sounded like. He turned around.

He walked back up the slope as quietly as he could without looking behind him. He rode all the way back to the cabin without checking another trap, and he did not return to that section of his line for the entire winter. The third event came in late November. The snow had started in earnest, and Callaway had brought in most of his higher traps.

He was working a lower line along a frozen meadow about four miles from the cabin, running fox sets in the kind of open country where a man can see half a mile in every direction. There was no way to be ambushed in country like that, and he wrote that this was the only reason he was out there at all. He had grown careful, watchful, and he had taken to muttering small things to himself just to fill the silence and to remind himself which voice in his head was his own. He was bending over a trap, working it with his gloved hands, when he heard a horse behind him.

Hooves on packed snow, the unmistakable rhythm of a horse at a slow trot. He turned. There was no horse. The meadow was empty.

He could see the tracks where his own mule had walked in, and his own boot prints, and nothing else. The hoofbeats had stopped the moment he turned around. He took a step back toward the mule. The hoofbeats started again, behind him.

He did not turn this time. He kept walking slowly, and the hoofbeats kept pace with him, not catching up, not falling behind, matching his stride. He could hear the soft creak of leather, as if there were a saddle on the invisible horse. He could hear the chuff of breath.

He could hear the small jingle of a bit. When he reached his mule, the sound stopped. He mounted up. He rode home.

He did not look back. That night he wrote one of the lines that would stay with anyone who ever read those journals. “The things in this country are not bound to the shapes they make. They can be a voice.

They can be a horse. They can be whatever they need to be to bring a man to them. And the only thing they all have in common is that none of them have ever once made a track in the snow. ”

By the spring of 1888, Callaway came down from the mountains with a respectable haul of pelts, sold them in Pinedale, and spent two weeks in town.

He asked his questions carefully, sideways, because he had seen what happened to men who came back from the high country talking about voices in the trees. They got laughed at, or worse, they got pitied, and pity in a frontier town was a kind of social death. He talked to old men. He talked to Shoshone hunters who came in to trade.

He talked to a French-Canadian priest named Father Aldebrand Petitclerc, who had been working a circuit through western Wyoming for thirty years and who, according to Callaway, had heard things in confession that he could not unhear. From those conversations, Callaway started to put something together. The Eastern Shoshone had a name for what lived in the Wind River Range. The rough translation Father Petitclerc gave him was something like “the ones who borrow voices,” or in another translation, “the ones who wear the sound of the dead.

” The Shoshone hunters told him these things had been in the mountains long before the first white trapper ever set foot there. They were not animals. They were not spirits exactly. They were something older.

They could not come into a camp where fires were properly tended and songs properly sung. They could not cross running water at certain times of year. They could not enter a dwelling unless they were invited, and the invitation could be as small as answering a question they asked. They hunted by sound.

They listened to people for a very long time before they tried anything. They learned voices the way a child learns a language, by repetition and patience. They would follow a man through the mountains for weeks before they ever spoke to him. By the time you heard your name from the trees, they had been studying you long enough to know what you would respond to.

Father Petitclerc told Callaway something else. He had buried four men in the previous decade who had died in ways the families asked him not to write down in the parish register. All four had been alone in the mountains. All four had been experienced outdoorsmen.

None of them had been killed by any animal anyone could identify. And in three of the four cases, family members had reported hearing the dead man’s voice calling from outside the cabin in the days following the burial. Callaway asked what the families had done. The priest said they had stopped answering the door.

One family had done worse. A woman at a homestead near the Sweetwater, on the second night of hearing her husband’s voice at the door, had opened it. She had been alone with her elderly mother. The next morning a neighbor who rode out to bring news of the funeral arrangements found the mother on the kitchen floor, dead of what looked like sudden heart failure.

The wife was gone. Her boots were still by the door. Her coat was still on the hook. There were no tracks leading away from the homestead in any direction, despite six inches of fresh snow.

The priest had been called in to bless the house before the property was sold. He told Callaway that in the upstairs bedroom he had felt something he could not describe, except to say that whatever had taken the woman was, in some way he did not understand, still in the house. He had blessed the rooms. He had said the proper words.

He had advised the family never to live there again. The homestead burned down two years later in a lightning strike, and Father Petitclerc told Callaway he considered the fire a mercy. Callaway went back into the mountains in May. He almost did not.

He thought about staying in town, taking a job at the livery, settling into the kind of small contained life that does not require a man to spend nights alone above timberline. But he had a trap line to run, and he had debts, and he had the particular stubbornness of a man who does not like to be chased out of a place he has earned the right to live in. The summer of 1888 was quiet. He heard no voices, no crying.

He saw a black bear in June and a cougar in August, both of which behaved like animals and left him alone. By the end of August he had almost convinced himself the previous autumn had been some kind of altitude sickness, or loneliness, or one of those strange psychological states men in remote places sometimes fall into. On August 30th he wrote, “Perhaps it was nothing. Perhaps the mind in solitude makes its own company.

”

The next entry is dated September 2nd. It is shorter than any other entry in the journal. It says only this: “Wendelin is dead. They heard him at the door for three nights.

His mother answered on the third. The cabin is empty now. I will not go back. ”

Wendelin Brusk had been killed in a logging accident outside of Dubois, Wyoming, on August 29th.

The accident had taken place two days before Callaway received word of it. The voice that had called Callaway’s name from the tree line in October of 1887 had been imitating a man who was still alive. Whatever had been in the trees that night had not been imitating Wendelin’s death. It had been studying him, practicing him, getting his voice ready the way a hunter sights in a rifle for later.

After Wendelin’s death, Callaway let the line cabin rot. He moved his operation thirty miles south to a stretch of country along the headwaters of the Popo Agie River, where he built a new cabin with a man named Olaf Bergstrom Sjoden, a Norwegian immigrant who had come to Wyoming after a failed homestead in Minnesota. Olaf was forty-four when they met, short and broad, with hair the color of pale straw and a beard he wore in two long braids in the old country style. He spoke English with a heavy accent and a slow precision, choosing every word as if he had paid for it in coin.

Callaway wrote that he was the steadiest man he had ever known. They ran a trap line along the Popo Agie for eleven years, from 1888 to 1899. During those years Callaway’s journal entries are calm, almost ordinary. He records the weather, the take, the births and deaths of people he knew in Pinedale and Lander.

Occasionally he mentions, in a careful and oblique way, that he had heard something at night, but he does not elaborate. He uses the same phrase every time. “The listening ones were near. ” Then he goes on to the next entry.

They had developed a system by 1893, he wrote. They never answered a sound they heard outside the cabin at night, not even if it sounded like the other one of them. If Olaf was outside chopping wood and called for him, Callaway would not respond unless he had heard Olaf go outside in the first place. They had a rule: three knocks at the door, never two, never four.

A specific phrase in Norwegian that Olaf had taught him, which they would say to each other before opening the door at night. They never sang the same song twice in a row, because the listening ones, Olaf said, learned faster from repetition. They kept the iron stove burning even on warm summer nights, because the listening ones, according to a story Olaf had heard from a Crow trader, did not like the smell of wood smoke that had been blessed by an old woman, and Olaf had paid an old Shoshone woman in Lander to bless their woodpile in the spring of 1890. There were other rules.

They never spoke each other’s full names out loud after dark, because a name spoken aloud at night was a thing that could be picked up and carried away, and the listening ones collected names the way a man collects coins. They never whistled. Olaf would not allow it. His grandmother in Norway had told him that whistling at night was an invitation to whatever was nearest, and the country around the Popo Agie was not country a man wanted to invite anything from.

They burned a small braid of sweet grass on the windowsill on the first night of every month, a practice an old Arapaho man had given them in exchange for a beaver pelt in the spring of 1891. They left a small bowl of milk on the porch on the longest night of the year, a Norwegian custom Olaf had carried from his mother. None of these things, Olaf told Callaway, would stop the listening ones from coming. But they would slow them down.

They would make the cabin a harder place to study. They would, in Olaf’s words, make the listening ones go and find an easier man somewhere else. Two hardened mountain trappers, respected and tough as the country they lived in, building their entire nightly routine around not being tricked by a voice from the dark. For eleven years they were not tricked.

Then, in October of 1899, Olaf Bergstrom Sjoden died in his sleep. He was fifty-five. Callaway wrote that he had simply not woken up one morning. No sign of struggle, no sign of illness.

His heart, Callaway thought, had just stopped. He buried Olaf behind the cabin in a grave he dug himself over two days in ground already starting to freeze. He carved the name into a slab of pine. He read a passage from the Norwegian prayer book Olaf kept by his bed.

Then he sat on the porch and cried for the first time in his adult life. He wrote, “I have not wept since I was a boy. I wept tonight for Olaf, who was the only friend I had left in this country. ”

The next night, the listening ones came for him.

At quarter past midnight he heard Olaf’s voice outside the cabin door, calling his name in that slow Norwegian way, asking him to open the door, asking him in English and then in Norwegian. The voice was perfect. It even had the small cough Olaf had developed in his last year, the dry cough he blamed on dust from the chimney. Callaway sat in the cabin for six hours holding his rifle, listening to his dead friend ask him to open the door.

The voice was patient. It did not get angry. It did not get loud. It simply asked, over and over in the same tone with small variations: “Callaway, please.

It is cold. I am hurt. The bear took my rifle. Callaway, your friend is here.

Callaway, please. ” It tried Norwegian. It tried the secret phrase. It got the phrase wrong.

The phrase had a specific cadence, and the listening one outside the door said the words in the right order but with the wrong rhythm. That, more than anything else, is what kept him from opening the door. The voice spoke for six hours. Just before dawn it stopped.

Callaway did not sleep. At first light he opened the door. There were no tracks. The frost on the porch boards was undisturbed.

The bowl of milk he had set out the night before was empty, but he could not say whether it had been drunk or had simply evaporated, and he wrote that he did not want to think too hard about which it had been. He left that morning. He packed everything he could carry on two mules and rode out of the Wind River Range without returning to that cabin, or so he thought. Three days into the ride out, camped along a creek eight miles, by his own reckoning, from any place he had ever heard the listening ones before, he heard Olaf’s voice again.

It came from the other side of his small fire. Callaway was sitting on a folded blanket, his rifle across his lap, the mules tied to a deadfall ten feet behind him. The fire was low. He had been about to put another piece of wood on it when the voice spoke.

Olaf said his name just once from across the fire. Callaway wrote that he did not look up. He did not move. He sat there with the firelight on his hands and listened to his dead friend ask him, very softly, to please look across the fire.

“Callaway, my friend, please look at me. I have come a long way. ” The voice said, “Callaway, I’m sorry I could not say goodbye. ” The voice said, “Callaway, the thing in the mountains, it lied to you about me.

I am here. I am real. Please look up. ”

Callaway did not look up.

He sat there until the fire burned down to coals. The voice spoke the entire time. He wrote that it was the longest hour of his life. When the fire went out and the camp was in full darkness, the voice stopped.

Callaway sat in that darkness with his eyes closed until the first gray of dawn showed in the east. Only then did he look up. There was no one across the fire. There were no tracks in the dust around the fire pit.

The mules were unharmed. He saddled them and rode out, and he did not stop again until he had crossed the South Fork of the Shoshone, which Olaf had once told him was a piece of running water old enough that the listening ones could not follow across it without permission. He sold his traps, his pelts, and his interest in the trap line to a younger man in Lander. He took a job as a stock manager on a ranch outside of Casper, where the country was open and you could see for miles and there were no thick stands of timber for things to hide in.

He stayed at that ranch for thirty years. He married a widow named Constance Whitford in 1906, when he was forty-five. They had no children. She knew nothing about his trapping years.

He never spoke of them. She died of pneumonia in 1928. Callaway lived alone in their small ranch house for fourteen more years, and during those years he wrote the final volume of his journal, the eleventh book, the one that no one in his family had ever been able to bring themselves to finish reading. The eleventh journal contains entries from 1928 to 1942.

Most are about the ranch, the weather, a horse he loved named Cassidy. But scattered through the margins and the back pages are entries that are not about the ranch. They are about a voice he started hearing in 1933, when he was seventy-two, sitting on the porch of his ranch house in central Wyoming, hundreds of miles from the Wind River Range. The voice was Olaf’s.

It came at night, from the line of cottonwoods at the edge of his property. It was patient. It was the same voice he had heard outside the cabin door thirty-four years earlier. It had not aged.

It did not sound any different. It still had the small dry cough. It had simply found him. Callaway wrote that he understood then something he had not understood before.

The listening ones did not need the mountains. The mountains were where they were easiest to find because they were quiet enough for them to practice. But once they had a voice, once they had learned a man, they could carry that voice with them. They could follow.

They could wait. They could wait for thirty-four years. In the autumn of 1935, his neighbor, an old rancher named Theron Hollister Vance, came to his door one afternoon with a strange question. Theron was a careful man, slow to speak, the kind who weighed a question for a long time before asking it.

He had ridden over from his place two miles south on a Tuesday, and he sat on Callaway’s porch and drank coffee for half an hour before he asked what he had come to ask. Had Callaway been out walking on Theron’s property the night before, around midnight, calling Theron’s name? Callaway said no; he had been in bed, asleep. Theron looked at him a long time.

Then he told Callaway that he had heard Callaway’s voice very clearly, calling to him from the cottonwoods on the western edge of his land, calling his name, asking him to come outside, saying something had happened, an emergency, that Theron needed to come quickly. Theron had not gone. His wife, Maribel Hollister Vance, had stopped him at the door. She had been a girl in Lander in the 1890s, and her grandmother had been Shoshone.

She told her husband calmly that the voice outside was not Callaway and that he should not, under any circumstances, open the door. Theron asked how she knew. Maribel said, “Because the voice in the cottonwoods is not breathing between words. ”

Callaway sat on the porch with Theron for a long time after that.

He did not tell Theron what he had carried with him out of the Wind River Range thirty-six years earlier. He did not tell him about Olaf. He did not tell him that the thing in the cottonwoods had spent two years learning his voice through the open kitchen window, listening to him talk to his horse, listening to him hum the small songs he hummed when he was alone. He simply thanked Theron for coming to ask, and he said that Theron’s wife was a wise woman and that he should listen to her in this and in all things for the rest of his life.

After Theron left, Callaway went into the house and closed every window. He did not open any of them again until the spring of 1936, and even then only the ones that did not face the cottonwoods. He wrote in 1935 that he had stopped sleeping with the bedroom window open. He wrote in 1937 that he had started keeping a lamp burning in the kitchen all night, because the voice did not seem to come into rooms with light in them.

He wrote in 1940 that the voice had begun saying things Olaf had never said. New sentences. Things it had been working on. He wrote in 1941 that the voice had begun occasionally to use his dead wife’s voice instead of Olaf’s.

The last entry in the journal is dated April 2nd, 1942. Callaway was eighty-one. He wrote: “The voice told me tonight that it has been waiting a long time for me to be tired enough. I think I’m tired enough now.

I think tonight I will go and see who has been calling me all these years. ”

He was found three days later by a ranch hand named Marcus Eustace Traubel, sitting on his porch with a journal in his lap. He had died in the night. There was no sign of violence.

The doctor who examined him, a Dr. Bertram Holcomb out of Casper, listed the cause of death as heart failure. The journal was given to his great-niece. The cabin in the saddle between the ridges, the one Callaway built with Wendelin Brusk in 1885, is still there, or rather what remains of it.

The roof collapsed sometime in the 1920s. The walls are mostly down. But the foundation stones are visible, if you know where to look. In 2007, a hiker named Solena Marchetti Vance was working as a wilderness ranger in the Wind River Range.

She was the great-granddaughter of Theron and Maribel Hollister Vance, the neighbors who had heard Callaway’s stolen voice in their cottonwoods on a Tuesday night in 1935. Maribel had lived to be ninety-six. She had told the story of that night to her son, who told it to his son, who told it to Solena when she was a young woman just starting her career in the backcountry. Solena had grown up with a warning: do not answer a voice from the trees, do not open the door for someone you cannot see, listen for the breath between the words, and if there is no breath, walk away.

On September 11th, 2007, she filed a formal incident report with her supervisor describing an event that had taken place two nights earlier near the headwaters of Bull Lake Creek. The same drainage where Callaway had heard his name from the tree line on October 14th, 1887. One hundred and twenty years earlier. According to the report, Solena had been camped alone in a small tent about two miles from the ruins of an old trapper’s cabin.

Just after midnight she heard a male voice from the tree line calling her name. The voice sounded exactly like her father, who had died of cancer six months earlier in Boise, Idaho. It asked her to come out of the tent. It said it was cold.

It said it had something important to tell her. Solena wrote in her report that she recognized the voice as her father’s and almost responded before something stopped her. The thing that stopped her was that the voice was not breathing between words. She listened for the small inhalation her father always made before a long sentence.

The pause for breath. The tiny human catch in the throat. It was not there. The voice from the trees was speaking on a single endless exhale, the way a thing speaks that has never in its entire existence needed to take a breath.

Solena stayed in her tent. The voice spoke for forty minutes. Then it stopped. In the morning she packed up her camp and hiked out.

She submitted her resignation as a wilderness ranger one week later. She has not returned to the Wind River Range since. There are mountains in the American West that have been listened to for longer than they have been mapped. There are voices that have been patient for centuries.

There are things that have learned us the way we have learned them, except they have been studying for longer, and they have nothing else to do, and they are not in any hurry. Callaway Truscott Renfield believed by the end of his life that the moment you answer a voice from the dark, you have given it something it can keep. The next time you are alone somewhere quiet, somewhere remote, somewhere the wind moves through the trees in a way that does not feel ordinary, and you hear someone you love call your name from a place you cannot see, you might consider, before you answer, whether the voice has aged the way a voice should age. Whether the cough is the cough you remember.

Whether the rhythm of the words is exactly right. Whether there is a breath between the words, or whether somewhere in the timber, something patient has been practicing.
