On August 20, 2016, 17-year-old student Evan Mitchell left his home in Moab, Utah, and was never seen again.
The next day, his pickup truck was found abandoned on a dirt road leading to St. Devil Canyon. Inside were a backpack without water, a torn tourist map, and an old knife. He had neither a phone nor a wallet with him.
Six years passed. In May 2022, a group of cavers exploring a new crevice stumbled upon an unknown cave. On the wet rock wall, they saw only one clearly carved word: Evan. Evan Mitchell was born and raised in Moab, a small town in eastern Utah, surrounded by red canyons and desert roads.
The place attracted tourists because of its national parks, but for the local teenagers it seemed like a trap. Seventeen-year-old Evan often told his friends about it:
“Moab is only beautiful for those who are passing through.”
He dreamed of moving to Salt Lake City and eventually to the East Coast. He was the middle son in his family.
His father worked as a mechanic in a garage, and his mother was a cashier in a grocery store. His older brother was already studying at a university in Colorado, and his younger sister was in high school. To his parents, he remained the quiet type who spent most of his time with a camera in his hand. His house was littered with prints: canyon landscapes, nighttime shots of the starry sky, and abandoned trailers by the roadside.
Photography was his passion. When he was 16, he saved up for a used digital camera, which he bought through an online ad. Since then, Evan spent most weekends in the desert, choosing routes usually only undertaken by experienced hikers. He knew all the narrow paths around Moab and could navigate by the shapes of the rocks and the position of the sun.
His friends remembered that he liked to go where no one else dared. But in the summer of 2016, his behavior changed. Teachers noticed that he was withdrawing, often sitting in the back row, and drawing strange shapes in his notebook—triangles with notches, similar to old icons. His classmates initially laughed at him, but then stopped paying him any attention.
Only a few close friends said that Evan seemed to be planning a trip, but he wouldn’t explain where or why. At home, he remained calm. But the family was tense. His mother said that her son would sit in front of his laptop for hours in the evenings, reading forum posts about caves and forbidden places in Utah. His father recalled finding ropes and carabiners in the garage several times that had never been there before.
Summers in Moab were hot, and most teenagers spent their time near the Colorado River or on bike paths. Evan, however, became increasingly withdrawn. When his friends asked him if he wanted to go for a ride with them, he declined.
“I have other things to do.”
One day, as his classmate Jamie Lewis recounts, he said:
“There are places here that nobody knows about. If you find them, you can leave a trace.”
At the time, the girl didn’t think much of it, but after his disappearance, those words came back to her like a disturbing prophecy. Family photos from that summer always show Evan with a camera. His pictures hardly show any people, only landscapes.
Stone arches, dried-up riverbeds, solitary bushes in the red sand. It seems as if he wants to capture the space without witnesses, as if he is preparing to stay there forever. By mid-August, the boy had almost completely stopped sharing his plans. His parents thought it was a normal developmental phase, but his older brother, who came home for a few days, noticed a strange determination in him.
He later recalled that Evan looked as if he had a secret he couldn’t tell anyone. In the evenings, he would go to a hill outside of town overlooking St. Devil Canyon. There he would sit with a notebook, taking notes. A neighbor who often walked her dog there saw him several times. He sat motionless, staring into the distance as if waiting for something.
A few days before his disappearance, his friends noticed another detail. He had printed out a map of the gorge and marked several points with crosses. When they asked him why, he simply said:
“We have to try.”
He explained nothing further. Those weeks in August were the last time anyone saw Evan as a normal person.
Then began a story that has become one of the darkest secrets of the Utah desert. On Saturday, August 20, 2016, at 7 a.m., Evans’ mother saw her son at home for the last time. She remembered him eating a quick breakfast of toast and coffee, taking the keys to his old Ford Ranger, and walking out into the yard.
He was wearing light jeans, a gray T-shirt, and a worn baseball cap with the logo of a local basketball team. That morning, a security camera at a gas station in downtown Moab recorded his car. The attendant later told police the boy had bought a bottle of soda and an energy bar, paid in cash, and behaved quietly.
He also noticed that Evan had bought two extra batteries for his flashlight. This receipt was later added to the case file. His pickup truck was seen around 10:10 a.m. on Highway 128, which leads to Sand Devil Canyon. A local family traveling to the national park at that time later confirmed this.
“The car looked familiar. We knew him from school. He was driving alone.”
At 11:20 a.m., a hiker from Arizona, returning from a tour, reported encountering a young man at an old information booth marking the start of an abandoned trail into the canyon. The man described the young man as wearing a light-colored T-shirt and carrying a camera over his shoulder.
He seemed focused and didn’t even say “hello,” the report states. This was the last confirmed witness to see Evan alive. After that, all trace of him was lost. No official tourist groups were registered at Sand Devil Canyon that day. The sun was rising higher, and the temperature exceeded 35°C (95°F). Under these conditions, it was difficult even for experienced travelers to go long without water.
The next day, August 21, around 9:00 a.m., some travelers found an abandoned Ford Ranger on a dirt road, several miles off the official route. The car was upright and showed no signs of an accident or struggle. The doors were locked, and the keys were nowhere to be found. Inside was Evans’ backpack, which contained an empty bottle, some energy bars, and a sketchbook, but neither a compass nor a water bottle, which he always carried on his hikes.
This immediately struck his parents as odd. Evan never went into the canyon without a full supply of water. An old knife in a worn sheath was also found on the front seat. The phone and wallet were missing. The vehicle registration and insurance were in the glove compartment, but there were no other clues.
A torn tourist map of the area lay on the floor. It bore several crosses he had made with a ballpoint pen at various points in the canyon. They were the same markings he had drawn in his notebooks. The car was parked in direct sunlight. Inside, it was stuffy and quiet, as if the boy had only left the car for a minute and intended to return.
But he didn’t. At 9:00 a.m. on August 22, 2016, Evan Mitchell’s mother called the Moab Police Department. Her son hadn’t come home for two nights, and his phone was turned off. The officer on duty initially tried to reassure the woman by explaining that teenagers often stay late in the mountains or visit friends.
However, after being informed about the car found the previous day, the tone of the conversation changed. The car was officially registered as abandoned, and the case was now classified as a missing person case. That same afternoon, the first search party assembled near Sand Devil Canyon. It consisted of 15 police officers and about 20 local volunteers.
Later, dog handlers from Salt Lake City and drones joined the search, used to comb through hard-to-reach areas. The official timeline is documented in the police reports. At 2:40 p.m. on August 22, the drones flew over the area surrounding the pickup truck. The footage showed only deserted slopes with no human footprints. At 7:00 a.m. on August 23…
…search dogs picked up a scent from the car, but it disappeared after 500 meters in the rocky terrain. The handlers said the heat and wind had completely exhausted the dogs. On August 24, search teams examined more than 20 kilometers of trails, including an abandoned hiking path. Not a single item or trace was found.
This week’s local newspapers ran the headline: “17-year-old disappears in canyon and police suspect heatstroke.” A spokesperson for the department said:
“The conditions this summer are particularly harsh. If the boy ran away from the car without water, his chances of survival were minimal.”
The family immediately rejected this version of events.
The father pointed out that Evan knew all the trails around Moab, had been hiking since childhood, and had never been without water. His mother insisted that he had been preparing for something special. He couldn’t have simply run away from home. His friends didn’t believe the official explanation either. They remembered his talk of places no one knew existed and maps with strange markings.
When the police reported finding a torn map in the car, it intensified their suspicions. Perhaps he had deliberately strayed from the main routes. The atmosphere in the town grew increasingly tense. In the evenings, residents gathered near a café on Main Street and discussed the news. Some believed the boy had tried to escape, others suspected foul play.
But there was no concrete evidence. Despite all the resources—drones, dogs, dozens of volunteers—the desert remained silent. The search lasted a week, then another. Not a single item, not a single clue. It was as if Evan had vanished into thin air among the red rocks. The official police report, dated September 1, 2016, contained only one sentence: “Probably lost and died of dehydration.”
For the parents, these words were unacceptable. They insisted their son knew the area well, and the absence of bones or personal belongings proved otherwise. Nearly four years passed. The Evan Mitchell case remained marked as unsolved in the police archives. In Moab, his disappearance was rarely mentioned, except on the anniversary of the tragedy.
The official reports seemed to cover everything. The boy had gotten lost in the desert and died from the heat. For the family, it was an empty version without evidence. The turning point came in the spring of 2020. In March, a group of geology students from the University of Utah arrived in the St. Devil Canyon area.
They were investigating erosion processes in the sandstone, measuring cracks, and creating maps. On March 2nd at 4:30 p.m., one of them, doctoral student Jason Reed, noticed a strange, carved marking. A symbol was found on one of the rock ledges. At a height of about two meters, the marking was clearly visible in the stone.
It was an isosceles triangle with a vertical line inside. The lines looked fresh and had been scratched with a sharp metal object. Reed took a photo of the discovery and posted it that evening on his Facebook account with the caption:
“I found a strange symbol on a rock in Sand Devil Canyon. Does anyone know what it means?”
The post quickly garnered comments. Most users joked about Native American pictograms or hiking symbols. But a few hours later, a friend of the Mitchell family saw the photo and sent the link to Evans’ mother. She reacted immediately. She had kept some of her son’s school notebooks, and the same symbol—a triangle with a slash through it—appeared dozens of times along the edges of these notebooks.
“This is the symbol of my son.”
She said so, and the next day she handed the notebooks over to the police. The authorities reached an official assessment. Experts confirmed that the carvings in the rock were very similar to the drawings in Evans’ notebooks. Even the proportions matched.
The report states that the symbol appeared in recent years. It’s possible it was created in 2016. The news was published in the local newspaper, the Moabs Sun News, with the headline: “Mysterious symbol in canyon. New lead in the Mitchell case.” The article sparked a wave of discussion. Some believed any tourist could have done it.
Others were convinced that it was Evan who left it behind to leave a trail. For the family, the discovery was the first real proof in four years. An artifact carved into the rock suddenly refuted the accidental death theory and gave hope that the boy had been at that spot and might have lived longer than officially believed.
At this point, the investigation, which had previously seemed hopeless, was reopened. The focus was no longer solely on the story of the missing teenager, but also on the mysterious symbols in the red desert rocks. After a photo of a strange symbol was posted on social media in the spring of 2020 and an article was published in the Moab Sun News, the Evan Mitchell case was once again thrust into the spotlight.
The news spread quickly among adventurous bloggers and explorers of abandoned places. Groups of searchers began arriving at St. Devil Canyon, some out of curiosity, others seeking proof that the boy had indeed left footprints. Locals reacted in different ways. For some, the new wave of expeditions was a source of hope.
Perhaps they would find something important now. For others, it was just another reminder of the tragedy. Police officially warned that the area was dangerous, but it was impossible to stop the influx of enthusiasts. Two years later, in May 2022, one of these groups, consisting of three cavers from Salt Lake City, explored the slopes three kilometers from where Evans’ pickup truck had been found.
After the spring rains, a landslide had occurred, opening a new passage at its base. The entrance was narrow, less than two meters wide, like a random crack in the rock. On May 11th at 10:30 a.m., the cavers decided to enter the passage. Flashlights illuminated the damp walls.
At first glance, nothing seemed out of the ordinary. Natural scratches and layers of sandstone. But after a few meters, they saw something that made them stop. The walls were covered with dozens of scratches, seemingly made at random with a sharp object. In this jumble, the word Evan stood out clearly. The letters were uneven, but easily recognizable.
They were almost half a meter high and positioned so they couldn’t be missed. The remains of an old flashlight lay nearby on the ground. The casing was broken, the batteries rusted. A little further on lay a knife with a broken handle, covered in corrosion. Both objects looked as if they had been there for several years.
Photos of the discovery were quickly forwarded to the police. Officers arrived the next day. The report stated: “The inscription ‘Evan’ was found carved into the cave wall at a depth of approximately 15 meters. Nearby were items resembling the personal belongings of the missing Mitchell.” This was a turning point for the locals.
While the official version had previously explained the disappearance as an accident, evidence now pointed to a deliberate act. Evan hadn’t just gotten lost; he had left his name in the darkness of the cave, as if he wanted to be found. This discovery changed the atmosphere of the case. What began as a random disappearance became a story with a clear trail, suggesting that more than a simple tragedy had unfolded in the canyon.
In June 2022, the cave where the inscription “Evan” was found was officially examined by forensic experts from Salt Lake City. The operation lasted three days, and the results were a shock to everyone following the case. First of all, the experts confirmed that the inscription on the wall dated back to around 2016.
They used the method of microscopic analysis of oxidation traces on the surface of the scratches. The conclusion was clear: the inscription was created around the time Evan disappeared. Exploring the cave revealed further strange details. In the corner next to the flashlight fragments lay a piece of fabric, torn with an uneven edge.
The laboratory confirmed that the fabric was a cotton blend with polyester, typical for T-shirts sold in those years. Traces of sweat and dust were found on the fibers, but DNA tests yielded no conclusive results due to the extensive decomposition of the material. Charred coal remnants were also found on the ground.
They lay in a small hollow, as if from an improvised fire. Nearby were stones stacked in a circle. Chemical analysis revealed that these were the remains of an ancient fire, dating from the same period as the inscription. It turned out that someone, and almost certainly Evan himself, had attempted to spend not just an hour, but at least several days in the cave.
This was a turning point for the police. Until then, they had believed Evan had disappeared and died in the desert, but now a new hypothesis emerged: the boy might have deliberately hidden himself in the cave. Investigators turned their attention back to Evan’s personal belongings, which were kept in his parents’ garage.
Among the items was an old laptop. It had already been examined in 2016, but the check had only been superficial. Technicians had merely reviewed the most important files and found nothing suspicious. The computer had been returned to the family. After its discovery in the cave, experts are now using modern tools to recover the deleted data.
This allowed them to recover browser history and forum correspondence, which proved crucial. The recovered data also included browsing history from visits to online forums. One of these was aptly named “Hidden Caves of Utah.” In the discussions on this forum, Evan went by the nickname “Sand Seeker.” Between April and July 2016, he left dozens of messages.
His posts were about unexplored rock crevices, ancient Native American tunnels, and caves that could be entered undetected. The police were particularly interested in the correspondence with a user named DeepPath. This correspondence had survived in the form of several threads in which participants discussed building shelters in rock crevices, finding water sources, and methods for navigating without maps.
DeepPath repeatedly made allusions in its messages:
“There are places that even the local guides don’t know about. You can stay there and nobody will find you.”
Investigators were unable to identify this individual. The IP addresses led to public Wi-Fi connections in various cities in Utah.
But the tone of the correspondence was disturbing, as if someone were deliberately pushing the boy to run away from home and embark on a dangerous experiment. The family reacted with pain. The idea that Evan wanted to go into hiding was unacceptable to his mother. She insisted that he could only have gone there under someone else’s influence.
The news caused a great stir in the city. The discussions divided people into two camps. Some said:
“He decided to escape the world. It was a conscious decision.”
Others were convinced that someone had exploited his gullibility and lured him into a trap. The investigation of the cave and the correspondence found changed the nature of the case.
This was no longer a case of random disappearance, but a story that suggested a carefully prepared plan or even outside influence. A new line appeared in the police report from July 2022: “The identity of the DeepPath user who was in contact with him the night before his disappearance must be determined.”
The case was reopened for a more comprehensive investigation. Now the focus was not only on the cave with the inscription “Evan,” but also on the mysterious interlocutor who may have known far more than initially apparent. When the results of the cave investigation were published in the press, interest in the Evan Mitchell case increased dramatically.
The media began mentioning other disappearances in the same area. At least three similar stories were found in the national park’s archives. A tourist from Nevada disappeared in 2008, a college couple from Colorado disappeared in 2011, and a traveler from Arizona disappeared in 2015. All of them were last seen near St. Devil Canyon.
None of them were ever found. For a long time, these facts remained scattered throughout the reports of various agencies. Only now have they been compiled, revealing that the disappearances were strangely concentrated in one area. Local newspapers wrote about the cursed ravine, and bloggers created interactive maps, marking all the locations linked to similar cases.
The speleologists who first entered the cave bearing the inscription “Evan” continued their explorations. They mapped every new passage, every crack in the rock. And gradually, a network of tunnels emerged, stretching for several kilometers into the depths of the canyon. Some of these passages were so narrow and dangerous that no one dared to traverse them without specialized equipment.
In August 2022, a group of researchers decided to return to the cave and venture further into the main chamber containing the inscription. After several hours, they came across a small niche in the wall. Inside was an old metal box that looked like an army ammunition container. It was covered in rust but still in good condition.
The box was carefully removed and handed over to the police. Inside, amidst shards of plastic and torn paper, they found the most valuable item: an SD card wedged between pieces of foam. It appeared damaged, the edges were burned, but after several attempts, the technicians managed to open some of the files. Several dark, blurry photos appeared on the screen.
The first image showed a narrow corridor with uneven walls, illuminated by the weak beam of a flashlight. The second was a rock fragment with scratches similar to those in the main cave. The third showed the vague shadow of a human figure on the wall. It could not be determined whether it was the photographer himself or someone else.
The police added the find to the case file as an artifact of unknown origin. This was another blow for the family. If Evan had a camera or a device for storing photos, it meant he had deliberately documented what he saw. So why were these pictures left in a box deep inside the cave? Investigators began comparing the data with that of other missing persons.
Maps showed that all the cases occurred within the same corridor system. A theory emerged. There was an entire network of caves that had been overlooked by tourists and even experienced guides for years, and this was precisely where people could disappear. A wave of rumors once again swept through the city.
Some spoke of secret cults, others of criminal hideouts. But the fact remained: a metal box containing a memory card was found in the cave, showing photos of shadows and dark passages. And now Evans’ case no longer looked like the ordinary disappearance of a teenager. It was developing into a story with the hallmarks of a deliberate mystery, hidden deep within the depths of St. Devil Canyon.
In the fall of 2022, the Utah State Police released the final report on the Evan Mitchell case. For the first time, it was officially confirmed that the boy had indeed been in the cave where his name, personal belongings, and an artifact containing an SD card were found. However, this was where the confirmed facts ended. Investigators determined that there was no evidence to suggest he had been there voluntarily.
There was also no confirmation that he had been lured there or forcibly brought in. The scenarios remained open. The most important paragraph of the report read as follows:
“Further investigations have failed to clarify the whereabouts of the missing person, the circumstances of their death, or a possible escape. The body has not been found. As no new evidence has been presented, the case is classified as unsolved.”
This wording was a cold shower for the family. The mother refused to sign the documents and reiterated to journalists:
“My son lives until his body is found.”
Every year, the sister brought the photos her brother had taken in the desert to the symbolic grave in the city cemetery.
In Moab, the incident took on a completely different meaning. The cave with the inscription became known as “The Named Cave.” Local children told eerie stories about shadows appearing on the walls and the voice of a boy calling for help. Tourism companies officially excluded the area from their itineraries, which only made it more appealing to adventure seekers.
Volunteers who repeatedly attempted to penetrate deeper into the tunnel system reported strange sensations, sudden temperature changes, rustling sounds in the darkness, and traces of old campsites that could not possibly have belonged to just one person. They found scratches on the stones that resembled the same symbols Evan had drawn. However, some of them looked older, as if they had been made long before his disappearance.
These details sparked a new wave of rumors. Some spoke of secret cults, others of criminal hideouts. Some even claimed there was an unknown network of caves in the gorges where people could disappear for years. The police officially warned that the cave entrance was dangerous and that entry was prohibited. However, this only reinforced the cave’s reputation as a cursed place.
The case culminated in a letter to the family dated November 22, 2022, stating that the Evan Mitchell case was officially closed as unsolved. There was no grave, only an empty plot in the city cemetery with a memorial plaque in Evan’s memory. Every year, his parents brought flowers there, his sister placed photos, and the cave bearing his name remained.
And anyone who dared to approach its entrance saw the carved word Evan. A silent testament to the presence of the boy who disappeared in August 2016. Whether he left the inscription himself or someone else remains unknown to this day. And along with this uncertainty comes the most unsettling of all questions: Whose traces still lie hidden in the dark corridors beneath St. Devil Canyon?
