Dyatlov Pass incident

The Dyatlov Pass incident resulted in the deaths of nine ski hikers in the northern Ural mountains on the night of February 2, 1959. It happened on the east shoulder of the mountain Kholat Syakhl (a Mansi name, meaning Mountain of the Dead). The mountain pass where the incident occurred has since been named Dyatlov Pass after the group's leader, Igor Dyatlov.

The lack of eyewitnesses has inspired much speculation. Soviet investigators determined only that "a compelling natural force" had caused the deaths. Access to the area was barred for skiers and other adventurers for three years after the incident. The chronology of the incident remains unclear because of the lack of survivors.

Investigators at the time determined that the hikers tore open their tent from within, departing 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 her tongue.
