ⓘ Dyatlov Pass incident

The Dyatlov Pass incident is an unsolved mystery to the deaths of nine ski hikers in the northern Ural mountains on the night of February 2, 1959. The incident happened on the east shoulder of the mountain Kholat Syakhl. The mountain pass where the incident occurred has since been named Dyatlov Pass after the groups leader, Igor Dyatlov. To this day, the incident has not been solved.

2. What killed the hikers?

It is not known what happened to the hikers. The most likely thing is that an avalanche hit them, and some of them struggled on until they died of cold and exposure. Only one hiker who left the group before the event happened survived. Six of the group members died of hypothermia and three of fatal injuries.


3. Theories

There are many conspiracy theories towards what killed the hikers. Many Russians believe that a local tribe called the Mansi people killed them for trespassing on their property. Others believe that the military had something to do with their death. High levels of radiation was found on their clothing so some believe that a missile misfired and crashed nearby the hikers.


4. What investigators discovered

Investigators at the time discovered that the hikers tore open their tent from inside, ran barefoot into heavy snow and a temperature of −30 °C −22 °F. Although the corpses showed no signs of struggle, two victims had fractured skulls, two had broken ribs, and one was missing parts of her face such as her tongue.

  • Released documents contained no information about the condition of the skiers internal organs.
  • There were no indications of other people nearby apart from the nine travelers on Kholat Syakhl, nor anyone in the surrounding areas.
  • Forensic radiation tests had shown high doses of radioactive contamination on the clothes of a few victims.
  • To dispel the theory of an attack by the indigenous Mansi people, Dr. Boris Vozrozhdenny stated that the fatal injuries of the three bodies could not have been caused by another human being, "because the force of the blows had been too strong and no soft tissue had been damaged".
  • There are no survivors of the incident.
  • Six of the group members died of hypothermia and three of fatal injuries.
  • Traces from the camp showed that all group members left the camp of their own accord, on foot.
  • large footprints, not human but humanoid in shape.
  • The victims had died 6 to 8 hours after their last meal.
  • The tent had been ripped open from within.
