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

That was explained away, as some wore the clothes of the others that worked near radioactive substances, and of course the ones that actually worked there.

@KariHikariOokami Because they don't want to talk about the supernatural. But rather stick with strictly "scientific plausibilites". It's RIDICULOUS quite frankly. Something VERY VERY bizarre happened to these kids.

Is that area prone to katabatic winds and slab-type avalanches? The Mansi are in the position to know. In a different vein, if temperatures outside were -30 Celsius, why sleep so skimpily dressed to start with? And, if you dash out of the tent into bitter cold after extracting your body from a sleeping bag, why not take the bag along? I grant the Swedish commentator that it takes long to put on clothes and boots in a state of shock, but why discard the protection you already had against cold in the tent? This is all the more bizarre when done by ten people, not just one or two. Some versions claim that the Soviet army got to the site before the rescue team, which suggests the evidence may have been heavily tempered with.

despite the two most plausible theatres of avalanche and hurricane like wind its still unclear why: 3:30 was there clothes was found with lagre amount of radioactive substance, it is likely possible that a nuclear test gone wrong caused the extreme blast wave cascading in to an avalanche, it explain why the cure left so hasty too as they would have awoke a deafening sound that would likely terrify them in to doing what they did and explain the radioactive material in some of there clothes sadly the records don't explicitly say what kind of material was it so it is hard to tell for sure but given secretive nature of the ussr and the time period of soviets testing hydrogen bombs it is the most likely scenario.

I am enthralled by this mystery! While the theories are *super* interesting, I don’t believe we’ll ever find out what happened to those hikers. All we can do now is take measures to ensure that nothing like this happens again: providing accessible and efficient communication throughout rural areas, and transparent law enforcement. (Unfortunately, that last one is less likely to ever occur, if at all.)

Knowing the Soviets and the fact that they wanted to close the case as quick as possible it was probably a botched nuclear missile. There's no record of one being launched but it's extremely easy to hide it. You just delete the record.

could have been that the enterance of the tent became blocked with snow, the tent might have been pitched further up from where it was found, im sure there could be a multitude of reasons they had to cut themselves out of the tent, it is what made them cut themselves out, why one set of tracks but two body sites. Radiation on the clothes of the injured group near the water, so the water carried particles from somewhere further up the mountain ?? could it have been a meteor strike near by, what kind of radiation was it. is it not true scientists can tell this and where it came from ??

That simulation shows just nice animation generated in Comsol but what density of snow one should consider to deform the human body so badly?? Was it a concrete to make such injuries? Any simulation in our university we try to verify on the practice....why such simulation has no verification? Second, why on the snow one could find trucks of hikers and also the tent was in tact if one consider that kind of avalanche! and also the skis were stuck in the snow! And, the most interesting part, how hikers with such insures could go so far from the tent??? To me it is very strength why this theory was considered on this channel at the first place...

Just saw a fantastic 3 part series by Russian INcdsr - Dima Maslennikov and none of these theories make sense. If there was an indeed an avalanche or high speed Katabatic wind that night , how did the tent keep standing? Also Dima goes on the location and the forest is almost 1.5 kms from the location of the tent, quiet a distance. The Water stream and the Cedar tree where the few bodies were found far deep inside the forest. It is only after seeing Dima's video you understand the terrain and both these theories seem even more implausible. But the mystery of the standing tent, seen in all old photos, is the biggest red herring for me. Strange!

Science is about facts, when you negate the most possible situation because it involves phenomenons that you don't understand and reject to believe then you are not being scientific nor logic. This is the problem of the mainstream media with every "paranormal" Phenomenon, if it looks like a conspiracy or implies unexplainable things, they just will try to find the most absurd theory to understand it from their view

First theory seems more plausible, if they felt there was an avalanche coming the best way to survive would be to make a run for the trees, whereas if it was due to the winds I doubt they would have come out of the tent in the first place as it would be impossible surviving the high velocity winds.
