Dyatlov Pass Incident, In the winter of 1959, nine hikers set off on a trek in the Ural Mountains of Soviet Russia. They never returned. Weeks later, their bodies were found in a shocking and mysterious state, raising more questions than answers. What happened to them that night? Why did they flee their tent half-dressed in freezing temperatures? And why did the Soviet government classify their case? Even today, over 60 years later, the Dyatlov Pass Incident remains one of the most bizarre and chilling unsolved mysteries in history.
Let’s dive deep into who these hikers were, where they were going, what was found, and the theories that try to explain the impossible.
The People Involved
The group consisted of nine hikers, mostly students from the Ural Polytechnic Institute. They were experienced in trekking and mountaineering.
Here are their names and ages:

- Igor Dyatlov (23) – The leader of the group
- Zinaida Kolmogorova (22) – One of the two women in the group
- Lyudmila Dubinina (20) – The other woman, known for her strong will
- Yuri Doroshenko (21) – A brave and physically strong member
- Alexander Kolevatov (24) – A physics student
- Rustem Slobodin (23) – An athlete and engineer
- Nikolai Thibeaux-Brignolles (23) – From a French-Russian family, an intelligent and skilled trekker
- Semyon Zolotaryov (38) – The oldest member, a war veteran
- Yuri Krivonischenko (24) – A cheerful and humorous personality
There was originally a tenth member, Yuri Yudin (21), who fell ill and had to turn back before the group continued their journey. He was the only one who survived.
Timeline of Events
January 23, 1959-The group left Sverdlovsk (now Yekaterinburg) by train.
January 25, 1959-They arrived at Ivdel, a town close to their starting point, then took a truck to Vizhaj, the last village before the wilderness.
January 27, 1959-The hike officially began. They skied into the Ural Mountains.
January 28 1959-Yuri Yudin, feeling unwell, left the group and returned home. This saved his life.
February 1, 1959-The group set up camp on Kholat Syakhl (which means “Dead Mountain” in the local Mansi language). This was their last known location.
February 12-20, 1959-The group was expected to return by February 12. When they didn’t, a search was started on February 20.
February 26, 1959-The search team found their abandoned tent half-buried in snow. It was cut open from the inside. Barefoot footprints led away from it into the wilderness.
February 27 – March 5, 1959-The first five bodies were found, some barely dressed, lying near a burned-out fire and in the snow.
March – May 1959-The remaining four bodies were discovered in a ravine. They had severe internal injuries, including crushed ribs and a fractured skull, but no external wounds. One hiker was missing her tongue and eyes.
The Unsettling Discoveries
When investigators examined the scene, they found shocking details:
- The tent was sliced open from the inside, meaning they cut their way out in panic.
- Their footprints showed they had fled barefoot or in socks, despite the freezing temperature.
- Some bodies were found close to each other, while others were scattered far away.
- Four hikers had severe internal injuries, like those seen in car crash victims, but with no external wounds.
- Radiation was detected on some of their clothing.
- Some had burns, others had weird orange skin and grey hair, as if affected by chemicals.
Popular Theories
Many theories try to explain what happened that night. Here are the most famous ones:
- Avalanche Theory – A sudden avalanche forced them to flee. But their footprints remained visible, and the injuries did not match an avalanche pattern.
- Military Testing – Some believe they accidentally walked into a Soviet military experiment involving secret weapons, radiation, or parachute mines.
- Paranormal Theories – Some suspect UFOs or strange energy forces caused the group’s panic.
- Infrasound Theory – Powerful winds created a low-frequency sound that caused paranoia, making them flee.
- Mansi Attack – Some believe the local Mansi people attacked them, but there was no sign of struggle.
- Yeti or Wild Animal – Some wild theories suggest a Yeti attack, but no animal tracks were found.
The official Soviet report only stated that the hikers died from an “unknown compelling force.” The case files were later classified and only released decades later, fueling speculation that something was being covered up.
Summary: Why Does This Mystery Still Baffle Us?
Even today, the Dyatlov Pass Incident is an unsolved puzzle. Here’s why:
- No single theory explains everything – The strange injuries, radiation, missing body parts, and bizarre behavior don’t fit neatly into any explanation.
- The Soviet government quickly closed the case – This led people to believe they were hiding something.
- New evidence still emerges – Some researchers continue to investigate, but no final answer has been found.
It remains one of the most frightening and fascinating mysteries in modern history.
