62-477: On February 2, 1959, a group of ski hikers led by Igor Dyatlov mysteriously perished on the east shoulder of Kyolat Syakhl (not Otorten, as is sometimes erroneously reported). This Dyatlov Pass incident is the main reason that people outside the immediate area in Russia have heard of this remote peak. The name of this mountain simply meant a "lack of game" for native Mansi hunters. The word kholat (meaning "death")

Numerous theories have been put forward to account for the unexplained deaths, including animal attacks, hypothermia , an avalanche , katabatic winds , infrasound -induced panic, military involvement, or some combination of these factors. Russia opened a new investigation into the incident in 2019, and its conclusions were presented in July 2020: that an avalanche had led to

These factors were not considered by the 1959 investigators who arrived at the scene of the accident three weeks later when the weather had much improved and any remains of the snow slide had settled and been covered with fresh snowfall. The harsh weather at the same time played a critical role in the events of the tragic night, which have been reconstructed as follows: According to

They were implicated in a 1978 case at Anaris Mountain in Sweden, where eight hikers were killed and one was severely injured. The topography of these locations was noted to be very similar according to the expedition. A sudden katabatic wind would have made it impossible to remain in

The snow slab, according to Greene, would probably have made loud cracks and rumbles as it fell across the tent, making an avalanche seem imminent. Kuryakov noted that although the skiers made an error in the placement of their tent, everything they did subsequently was textbook: they conducted an emergency evacuation to ground that would be safe from an avalanche, they took shelter in

However, others in the group appear to have acquired additional clothing (from those who had already died), which suggests that they were of a sound enough mind to try to add layers.

Igor Dyatlov, a 23-year-old radio engineering student at the Ural Polytechnical Institute (now Ural Federal University ), the leader, assembled a group of nine others for the trip, most of whom were fellow students and peers at the university. The initial group consisted of eight men and two women, but one member later returned due to health issues. Each member of

First of all, the ICRF investigators (one of them an experienced alpinist ) confirmed that the weather on the night of the tragedy was very harsh, with wind speeds up to hurricane force, 20–30 metres per second (45–67 mph; 72–108 km/h),

This was a division of the Sverdlovsk Committee of Physical Culture and Sport, and they confirmed the group of 10 people on January 8, 1959. The goal of the expedition was to reach Otorten ( Отортен ), a mountain 10 kilometres (6.2 mi) north of the site where the incident occurred. This route, estimated as Category III,

Overnight, something caused them to cut their way out of their tent and flee the campsite while inadequately dressed for the heavy snowfall and subzero temperatures. After the group's bodies were discovered, an investigation by Soviet authorities determined that six of them had died from hypothermia while
1426-564: The paranormal . Indeed, many of those who had remained silent for thirty years reported new facts about the accident. One of them was the former police officer, Lev Nikitich Ivanov ( Лев Никитич Иванов ), who led the official inquest in 1959. In 1990, he published an article that included his admission that the investigation team had no rational explanation for the incident. He also stated that, after his team reported that they had seen flying spheres, he then received direct orders from high-ranking regional officials to dismiss this claim. In 2000,

1550-559: The ICRF investigators, the factors contributing to the tragedy were extremely bad weather and lack of experience of the group leader in such conditions, which led to the selection of a dangerous camping place. After the snow slide, another mistake of the group was to split up, rather than building a temporary camp down in the forest and trying to survive through the night. Negligence of the 1959 investigators contributed to their report creating more questions than answers, as well as inspiring numerous alternative and conspiracy theories. In 2021,
1612-473: The area now serves as a memorial to the group. It is located about 500 metres (1,600 ft) to the east-southeast of the actual site of the final camp. In 1959, a group was formed for a skiing expedition across the northern Urals in Sverdlovsk Oblast , Soviet Union . According to Prosecutor Tempalov, documents that were found in the tent of the expedition suggest that the expedition was named for

Several Mansi were interrogated, but the investigation indicated that the nature of the deaths did not support this hypothesis: only the hikers' footprints were visible, and they showed no sign of hand-to-hand struggle. Although the temperature was very low, around −25 to −30 °C (−13 to −22 °F) with a storm blowing,
1736-424: The bodies were unnaturally manipulated, on the basis of characteristic livor mortis markings discovered during an autopsy, as well as burns to hair and skin. Photographs of the tent allegedly show that it was erected incorrectly, something the experienced hikers were unlikely to have done. A similar theory alleges the testing of radiological weapons and is based partly on the discovery of radioactivity on some of

There are indeed records of parachute mines being tested by the Soviet military in the area around the time the hikers were there. Parachute mines detonate while still in the air rather than upon striking the Earth's surface and produce signature injuries similar to those experienced by
1860-452: The camp. Between the pine and the camp, the searchers found three more corpses: Dyatlov, Kolmogorova, and Slobodin, who died in poses suggesting that they were attempting to return to the tent. They were found at distances of 300, 480, and 630 metres (980, 1,570, and 2,070 ft) from the tree. Finding the remaining four travelers took more than two months. They were finally found on 4 May under four metres (13 ft) of snow in

However, radioactive dispersal would have affected all, not just some, of the hikers and equipment, and the skin and hair discoloration can be explained by a natural process of mummification after three months of exposure to the cold and wind. The initial suppression by Soviet authorities of files describing

1984-418: The darkness of night, they got separated into two or three groups; one group made a fire (hence the burned hands) while the others tried to return to the tent to recover their clothing since the danger had passed. But it was too cold, and they all froze to death before they could locate their tent in the darkness. At some point, some of the clothes may have been recovered or swapped from the dead, but at any rate,
2046-506: The dead were only partially dressed. Some had only one shoe, while others wore only socks. Some were found wrapped in snips of ripped clothes that seemed to have been cut from those who were already dead. Journalists reporting on the available parts of the inquest files claim that it states: At the time, the official conclusion was that the group members had died because of a compelling natural force. The inquest officially ceased in May 1959 as
2108-444: The deaths. Survivors of the avalanche had been forced to suddenly leave their camp in low-visibility conditions with inadequate clothing and had died of hypothermia. Andrey Kuryakov, deputy head of the regional prosecutor's office, said, "It was a heroic struggle. There was no panic. But they had no chance to save themselves under the circumstances." A study led by scientists from EPFL and ETH Zürich , published in 2021, suggested that

On 11 July 2020, Andrey Kuryakov, deputy head of the Urals Federal District directorate of the Prosecutor-General 's Office, announced an avalanche to be the "official cause of death" for the Dyatlov group in 1959. Later independent computer simulation and analysis by Swiss researchers also suggest avalanche as the cause. Summarizing Kuryakov's report in The New Yorker , Douglas Preston writes, The most appealing aspect of Kuryakov's scenario
2232-461: The film-makers. The narrative line of the book details the everyday life and thoughts of a modern woman (an alter ego of the author herself) who attempts to resolve the case. Despite its fictional narrative, Matveyeva's book remains the largest source of documentary materials ever made available to the public regarding the incident. Also, the pages of the case files and other documentaries (in photocopies and transcripts) are gradually being published on
2294-520: The first five bodies were found. A medical examination found no injuries that might have led to their deaths, and it was concluded that they had all died of hypothermia . Slobodin had a small crack in his skull, but it was not thought to be a fatal wound. An examination of the four bodies found in May shifted the narrative of the incident. Three of the hikers had fatal injuries: Thibeaux-Brignolles had major skull damage, and Dubinina and Zolotaryov had major chest fractures. According to Boris Vozrozhdenny,
2356-432: The force required to cause such damage would have been extremely high, comparable to that of a car crash. Notably, the bodies had no external wounds associated with the bone fractures, as if they had been subjected to a high level of pressure. All four bodies found at the bottom of the creek in a running stream of water had soft tissue damage to their head and face. For example, Dubinina was missing her tongue, eyes, part of
2418-441: The group decided to set up camp there on the slope of the mountain, rather than move 1.5 kilometres (0.93 mi) downhill to a forested area that would have offered some shelter from the weather. Yudin speculated, "Dyatlov probably did not want to lose the altitude they had gained, or he decided to practice camping on the mountain slope." Before leaving, Dyatlov had agreed he would send a telegram to their sports club as soon as
2480-461: The group of four whose bodies was most severely damaged were caught in an avalanche and buried under 4 meters (13 ft) of snow (more than enough to account for the 'compelling natural force' the medical examiner described). Dubinina's tongue was likely removed by scavengers and ordinary predation. Evidence contradicting the avalanche theory includes: A review of the 1959 investigation's evidence completed in 2015–2019 by experienced investigators from
2542-415: The group returned to Vizhai. It was expected that this would happen no later than 12 February, but Dyatlov had told Yudin, before he departed from the group, that he expected it to be longer. When the 12th passed and no messages had been received, there was no immediate reaction, as delays of a few days were common with such expeditions. On 20 February, the travellers' relatives demanded a rescue operation, and

2604-483: The group was an experienced Grade II -hiker with ski tour experience and would be receiving Grade III certification upon their return. At the time, Grade III was the highest certification available in the Soviet Union and required candidates to traverse 300 kilometres (190 mi). The route was designed by Dyatlov's group to reach the far northern regions of the Sverdlovsk Oblast and the upper streams of
2666-454: The group woke up in a panic (...) and cut their way out the tent either because an avalanche had covered the entrance to their tent or because they were scared that an avalanche was imminent (...) (better to have a potentially repairable slit in a tent than risk being buried alive in it under tons of snow). They were poorly clothed because they had been sleeping, and ran to the safety of the nearby woods where trees would help slow oncoming snow. In

And by the late 1980s, all Dyatlov files had been released in some manner. International Science Times posited that the hikers' deaths were caused by hypothermia, which can induce a behavior known as paradoxical undressing in which hypothermic subjects remove their clothes in response to perceived feelings of burning warmth. It

Later, the army and militsiya (police) forces became involved, with planes and helicopters ordered to join the operation. On 26 February, the searchers found the group's abandoned and badly damaged tent on Kholat Syakhl . The campsite baffled the search party. Mikhail Sharavin, the student who found
2852-468: The hikers buried with the severe injuries observed. Another hypothesis popularised by Donnie Eichar 's 2013 book Dead Mountain is that wind going around Kholat Syakal created a Kármán vortex street , which can produce infrasound capable of inducing panic attacks in humans. According to Eichar's theory, the infrasound generated by the wind as it passed over the top of the Holatchahl mountain
2914-473: The hikers: heavy internal damage with relatively little external trauma. The theory coincides with reported sightings of glowing, orange orbs floating or falling in the sky within the general vicinity of the hikers and allegedly photographed by them, potentially military aircraft or descending parachute mines. This theory (among others) uses scavenging animals to explain Dubinina's injuries. Some speculate that

Contradictory results were obtained: one of the experts said that the character of the injuries resembled a person knocked down by a car, and the DNA analysis did not reveal any similarity to the DNA of living relatives.
