What killed 9 hikers in 1959?
✉️ Sign up for our newsletter:
In February 1959 a group of hikers disappeared in the remote Ural Mountains of Western Siberia. A search party found their tent weeks later, abandoned along with all of their equipment. Frozen bodies were found 1,500 meters away, mysteriously underdressed for the weather conditions: most weren’t wearing shoes or gloves, and some were just in their sleeping clothes. Even stranger, three of the hikers had suffered major internal trauma - broken ribs and a fractured skull - and two were wearing clothes contaminated with radioactive substances.
Nonetheless, the lead Soviet investigator closed the criminal case into the hikers’ deaths, concluding that an “overwhelming force” is what drove them from the tent. Theories ranging from rare weather events to conspiracy to UFOs have developed ever since, to explain what is now called the Dyatlov Pass incident. But two plausible theories, each involving an “overwhelming force” may finally explain what happened that night.
It could have been a delayed slab avalanche. The hikers dug a platform into the slope of Kholat Syakhl to pitch the tent, and a scientific model published in January 2021 demonstrates that this, combined with strong downslope winds that accumulated snow above the tent, triggered a deadly slab avalanche. This type of avalanche can occur even in places not known for avalanches and can cause injuries consistent with the ones some of the hikers sustained.
It also could have been a strong “katabatic wind,” a powerful wind that travels down a mountain slope, picking up speed under the force of gravity. In this scenario, a strong wind can become near-hurricane level very suddenly. If this happened the night of the incident, it could explain why the hikers would have abandoned their tent so quickly, as the powerful wind would potentially tear the tent apart. The mysterious internal injuries that some sustained are explained by a snow den the hikers dug for shelter collapsing on top of them.
Both theories offer potential solutions for what drove the hikers to suddenly abandon their tent, and why some were so severely injured. Ultimately though, since there were no survivors, many of the questions surrounding the case will likely never be answered.

One of the things that remains unexplained about the Dyatlov Pass incident is the radioactive substances found on pieces of clothes that Dubinina and Kolevatov were wearing. The expert testimony in the original radiation analysis report makes it clear that the radiation was unusual. The 1959 analysis included an experiment involving washing the clothes of the hikers - which they found reduced the level of contamination. The expert then emphasized that the bodies were found in running water. Meaning the level of radioactivity detected, which was excessive when the bodies were found, would have been significantly higher at the time of their death. Check out the original radiation analysis report, along with all of the other case files scanned and translated at, an amazing resource that has compiled many of the original documents related to the case: -Thanks for watching, Coleman

@witchy90210 yes but not in the levels presented. I believe the two radiated students either worked with nuclear physics for a job or at the school they attended

My personal opinion is that the cause of the tragedy was weather/nature related. I think that's the only cause which can explain why they left their tent in a hurry at first, but didn't go far and eventually tried to come back. I can't really imagine how could that be possible if they were pursued by some people or animals.

Russian blog writer and former soviet forensic expert Alexey Rakitin wrote an impressive book about this mystery (avaialable only in Russian language, unfortunately), where he brought up every imaginable explanation of this mystery - from an avalanche, to internal conflict within the group, to a raid by soviet special forces, to an attack by animals, to an attack by escaped convicts or native Mansi people. And he debunked literally all of them. That's the most chilling part about this story - there is not a single strong explanation to this story.

Were any of the scientist left handed by chance the damage looks similar to someone who would attack with a blunt object in the left hand. Also the damage on the women looks like a personal grudge or maybe the attacker wanted her and was denied.

Alright but let’s not forget about the high level of radiation on the bodies and not too sure if the force of snow collapsing on them is equivalent to that of a bomb blast

1. First witness photo the photo taken from within the tent, of a large face looking down from above the outside of the tent indicates the yeti photo and witness material in writing in my opinion clarifies that. That face peering into the tent was enough to scare them away. A yeti was proven by photos Easy ti see the circumstances Very sad. The radio activity on their bodies could be from their previous University classes.

Hey, just like a scene from the horror movie "secrets of chernobyl". At that scene, the tourists were trapped in their minivan because of an engine problem, and then some wild dogs howling just near the windows made them lose their nerves and abandon the minivan. (they eventually died of various causes)

Worth mentioning that many materials of this case are STILL CLASSIFIED more than 60 years after the tragedy. I doubt that an accidental death caused by an avalanche would require anything to be classified.

They left the tent to get away from something happening at the site of the tent. Has to be. If it were generalized wind or a small local avalanche, there's no reason to move 1,500 meters away in a frenzy because, isn't the wind all around you? Experienced people like these wouldn't seem to be spooked by a small avalanche either. Something unnatural was happening at the location of the tent which they all fled as fast as possible- the ones without gear eventually stopped and realized they were doomed unless they went back (two decided to freeze instead of even trying) while those with gear kept on going into the woods to hide from something that happened at the tent. They didn't keep moving, they hid- meaning they didn't think there was any way to outrun it.

I've watched other videos about this. This video did not mention that what made the injuries so bizarre is that there were no bruises. Basically to inflict damage inside the body the first that had to be damaged has to be the skin. Or technically physical trauma creates bruises. If you watch all the other videos about this there is always a mention about this since the injuries without the bruises is one of the reasons that made these deaths interesting yet bizarre.

Theres a theory by the content creator 'Lemino' that theories that a stove setup inside the tent managed to set it alight, causing the hikers to cut the tent open from the inside in a panicked attempt to escape, leaving their clothes inside, though there's nothing that's been found to my knowledge that would illude to a fire like say burned or scorched material.

Military activity made the native people think the mountain goddess was annoyed by the hikers trespassing.. So they smoked the hikers out and killed them. One native man admitted "we killed them" before disappearing

I think one of them went nuts, killed one or two, and everyone ran. The bodies were taken to the ravine. They wouldn't leave their tent because of wind. And the tent was still no avalanche...nope.

I feel like it was probably the katabatic winds with the evidence provided. But if you want to go purely of speculation i find a possible chemical explosion likely. They were scientists. And sometimes people do thinks they think will be fun that goes wrong. I've heard speculations of colourful lights in the sky that night maybe they had made some kind of fireworks and that's what went wrong. I don't know pure speculation

I'm a open minded person, but maybe some wild animals attack them during the night, maybe bears, wolf's I don't know if those animals exist on those regions, but maybe some wild animals attack them during the night, the only way to leave the tent was cutting the tent, and the weather do the rest.

Maybe it was a deadly mixture of both katabatic winds and slab avalanches.. I think it could be also a one in a trillion case of mass hysteria? Like a group induced psychosis of the cold weather and fear.. I think radon gas from the earth would explain the radiation as radon is drawn to pressure on the surface. An example would be that houses in the uk near mines and light ground suffer from radiation exposure ( Higher risk of lung cancers and motor skill diseases. ) Final note: I think this a one in a trillion event that had 3 to 4 known phenemon thrown into one single event, we simple minded humans probably cant grasp the mere possibility of such events taking place at one time.. I mean the universe came from nothing so anything is possible. :D
