One of the more haunting and confusing unexplained stories is the mystery at Dyatlov Pass. It borders on the line between a true crime story and a natural phenomenon occurrence. What happened to the nine hikers who died under mysterious circumstances while camping in 1959? Certain aspects of the case are genuinely terrifying, even if no crime was committed. In the following, I concentrate on some of the most unusual circumstances of the case.

On the night of February 1, 1959, nine hikers died under mysterious circumstances while camping in the Ural Mountains. The hiking party included Yuri Doroshenko, Lyudmila Dubinina, Igor Dyatlov, Aleksander Kolevatov (guide), Zinaida Kolmogorova, Yuri Krivonischenko, Rustem Slobodin, Nikolay Thibeaux-Brignolle, and Semyon Zolotaryov. Most were students of a nearby university. All of them were Grade II hikers and skiers. Upon completion of the challenging expedition to Gora Otorten Mountain, they would receive the prestigious certification of Grade III Hikers. Grade III certification was the highest hiking achievement in the USSR and fueled their ambition to finish the ill-fated trek.

Ten days into the trip, on February 1, 1959, something truly petrifying happened to the nine hikers. After they had eaten and were getting prepared to sleep, but before they set up their cumbersome heating stove, something in the night disrupted them to the point that they felt compelled to cut themselves out of their tent. According to David Bressan’s article in Forbes, Mystery At Dyatlov Pass“That evening, an unknown event caused the group to cut their way out of the tent and sent the shoeless and underdressed hikers into the freezing night, with temperatures below -22°F.” At this point, it is possible that they quickly separated into three groups as the wind, cold, and complete darkness would have been entirely disorienting. Not to mention the high level of fear that was compelling them to flee in the first place.

When rescuers first discovered the tent cut marks, they falsely assumed that the tent had been slashed open from the outside. This assumption propelled the theories of foul play. Later in the investigation, it was determined that the hikers had cut the tent from the inside. According to Nathan Chandler’s article The Dyatlov Pass Mystery: Were the Hikers Murdered?, “A line of footprints indicated that the nine people had walked away at normal speed, but some just wore just one shoe or were totally barefoot.” The position of footprints indicated the party walked through the snow at an average pace. These circumstances led investigators ultimately to believe that no other party was involved.

Cedar Tree

From there, Krivonishchenko and Doroshenko stopped down the hill nearer to the tree cover about 1.5 km from the tent. There, by a cedar tree, they built a campfire. They must have been too scared to return to the tent, or the wind was so strong that it was impossible to reclimb the hill. 

Krivonischenko and Doroshenko’s remains were found by the cedar tree wearing only underwear. Krivonishchenko was face up with damage to his eyes and face that investigators suspected was made by a bird. There was also evidence he bit off a piece of his knuckle. Was this done to stay awake or to stifle a cry? Doroshenko’s hand was burnt. Did he try to warm his hand by the fire so much so that he burnt himself? The search party discovered evidence that someone attempted to climb a nearby tree, presumably to see the tent. Or perhaps they cut the branches down for the fire. 

Map of the Area

Dyatlov, Kolmogorova, and Slobodin were found 300-630 meters from the cedar tree at varying distances and in poses that suggested they were attempting to hike back to camp. According to Donny Eichard’s book Dead Mountain: The Untold True Story of the Dyatlov Pass Incident, Rustem Slobodin’s “breath had melted the surrounding snow, suggesting that Rustik had been alive for some time after he fell. But what is most startling is the front of Rustik’s head, which is deeply discolored, as if he sustained a blunt force to the head.” All three were found wearing more clothing than Krisvonischenko and Doroshenko. 

The most likely scenario is the clothing was taken off or cut off of Krisvonischenko and Doroshenko by the other party members to keep the rest of them warm. However, there have been documented cases of “paradoxical undressing” in fatal hypothermia. Individuals experiencing severe cases of hypothermia feel as if their skin is burning. To relieve this burning, they begin to undress in a feeble attempt to ease the pain.

The rest of the group was not found until May, 70 meters from the fire pit. Three of these hikers sustained blunt force trauma injuries. Two had fractured ribs, and Kolya’s skull was fractured. Kolevatov had minor injuries but none were fatal, and his cause of death was ruled hypothermia. The medical examiner referred to their injuries as violent and said that the hikers encountered a compelling force. 

Furthermore, one person, Dubinina, was found with her tongue missing. The description of this in the autopsy, however, is so vague that it is hard to determine if it happened while she was alive or postmortem. It is certainly possible that part of her tongue could have been eaten by animals or microorganisms, but the lack of description does not help clear up the mystery. The coroner did list her stomach contents as containing 100 grams of coagulated blood, leaving many to speculate that her heart was pumping when the tongue was removed.

Searchers also found evidence of a makeshift den, meaning perhaps Kolevatov gathered sticks and clothing to lay on the ground in an effort to insulate the hikers from the freezing ground.

In his book, Eichard lays out a recreation of the night in question, based on the evidence and expert opinion, arguing that Kilevatov was the one who cut the clothing off Krivonishchenko and Doroshenko. Perhaps the least injured by their fall, Kolevatov attempted to get help for his injured friends and stumbled upon the fire. Unfortunately, Krivonishchenko and Doroshenko had already succumbed to hyperthermia, so he took their clothing to help the injured three. Unfortunately, his effort was in vain, as all would be dead before 3:00 am. 

There is no shortage of theories on what happened to the Dyatlov Pass hikers. Natural phenomena theories include an avalanche, Kármán vortex street (a whirlpool-like wind phenomena that is inaudible but extremely disorienting to the human ear), ball lightning, or a land hurricane. The criminal or more sinister theories include: Mansi natives perpetrating an attack in retaliation for the decimation of sacred ground; KGB agents marching the hikers down the hill because they saw something they shouldn’t, leaving left them to die from the elements as they searched for their tent; some sort of altercation between group members that led to murder; or, perhaps, the group made enemies with local loggers on their journey in and were killed. I think that all of these theories are a terrifying possibility. This is one story that continues to puzzle and haunt readers.

    Hey Christine, I’m Viswanath from India. I also enjoy crime mysteries and I happened to come across your website while browsing. Apparently, the Soviet authorities concluded that some ‘natural force’ caused their deaths in this case. Do you think it is convincing enough?

    • Christine Christine

      Thanks for reading and for taking the time to comment. Well, I do think it’s possible the hikers were killed by a “natural force,” but in my opinion that’s too vague. I would want to know what exact natural force and how. And evidence supporting it.


    Well I researched a bit, so here they all were Russian and were sort of local. Just making a point. So I asked why would they slash their tent?. Even if natural occurrences were to take place, the best possible would have been to take their tent or stay with it, but why slashed? This then leads to one possibility I think of – They were scared of something, something very terrifying that they didn’t bother to open their tents, According to local mansa(trials living there), they had myths about large birds and one eyed giants( cyclopses). But the strangest part is after that. While they finish escaping, about three die from hypothermia but the rest appear to major fractures and internal bleeding, which in my consideration could have been only one thing – an explosion (don’t know of which kind). The last part is about the tounge, it didn’t make the most sense but maybe my explanation might be right – The companies mining around these parts were classified as illegal at that time, so they made a facade that a local legend had come true to keep people out, now the next part is that these students may have accidently entered the area. So they reenacted a figure (don’t know how) and managed to scare them, but that was not enough, so they killed them, after that they yanked out the tounge to provide the locals a fear. Although I think this might be incorrect, since the stride of the group was uncanny, this is the best I can do 🙂

      Thanks for reading and for sharing your insights! The tent being cut has always puzzled me too. And I’m intrigued by your explanation of the missing tongue. Although I think most likely it was taken by natural causes, it would be good way to send a message to others about being silent on anything they see in the area.

  11. Trinity Trinity

    Did the officials ever do a tox screening?
    Sounds like they had been poison or drugged

    • Christine Christine

      Hi Trinity – such a weird case! Now my opinion has totally changed. If you get a chance check out The Prosectors podcast and their coverage of this case. They have a multipart series on it that presents a lot of intriguing theories!

  12. En En

    If they were scared that much to have to cut their tent from the inside out they wouldn’t have been found only 70meters from the tent the following may. I mean knowing Russia it could have been a government project they were piloting – taking advantage of some hikers in the area. In the western world we used MK ultra on various occasions this could have been something more technology based. We wont get facts on this especially if the government is involved.

    Another theory is maybe some crazy drug experience – maybe they took some bad acid had a bad trip and ended up scared of their own illusions. This may explain why some were badly wounded and some died of hyperthermia. Or maybe the bad injuries were caused by a bad fall while on the run.

    definitely suspicious in nature and an odd one. I guess the autopsy would of reveled if they had any drugs in them if they did toxicology reports back then.

    • Christine Christine

      Hey En. Thanks for reading! If you’re intrigued by this case check out The Prosectors podcast multiple episode series on it – it’s fantastic.
