Two theories for an unsolved Soviet mystery

What killed 9 hikers in 1959?

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

    • Redthirst No, it’s not the Kyshtym disaster-the Dyatlov group was too far away for their clothing to be radioactive. They were found too far to the northwest for the radiation from Kyshtym to have had such an effect on their clothing.

    • @Henrik Nordin yeah it's a shame vox didn't know this, makes the radiation super understandable. I think they died do to a rapid pressure change, even through I'm not very knowledgeable on the subject.

  • We need to study if alcohol's effect makes people take off their clothing during hypothermia. At least in Russia conventional wisdom is when you are about to freeze one should drink alcohol. My mom is kinda OCD person she always told me frozen people are always found naked. She hates when i go on adventures she has many stories. I think it's the easiest explanation.

  • It was a Yeti attack. That's why the tent was ripped open and its inhabitants had fled in horror, nearly naked, into frigid abyss. The four that suffered terrible injuries were killed by the Yeti. It took them to one of its layers nearby, but abandoned them before it could finish consuming them when the ice shelter collapsed in the subsequent avalanche. There is definitive proof that they were being stalked by the Yeti in photographs developed from the film in their cameras. The local indigenous people know all about it. The radiation was likely from the Yeti having, at some point, unwittingly ventured into one of the many contaminated areas created by the Soviet government. This is all fact, but the deep state cover up continues to this day, and has been joined by the West. And Joe Biden criminally stole the election while trump is the epitome of integrity and character. 🤣

  • Thanks. "Slab avalanche" is a term begging for a catchy portmanteau! I vote for the obvious 'slabolanche'! Whatever happened to these people was a tragedy. As a scientifically-minded person, I do believe there's always a reason, and that the human mind can (eventually) grasp it. Whether humans can ever truly find out a given thing is another matter entirely! I acknowledge that there will always be questions we can't answer. I accept that as an axiom. Gödel's Incompleteness Theorem doesn't only apply to logic & math! It's an inherent principle that applies to *_any system_*, including human knowledge. So, there will always be mysteries, and there will always be events (or cascades of events) that break the best planning, or the most 'secure' or 'fool-proof' of systems. tavi.

  • Probably an grizzly bear attack they heard the. Roar and ran into the woods where three of them died from hypothermia three must've tried to fend off the bear causing them injures so once the group gets to a certain point they send three of the best condition people back up to get gear while leaving the three injured people with one person to take care of them which ended in there death
