here's an excerpt that gives the overview
The Dyatlov Pass incident was an event that took the lives of nine hikers in mysterious circumstances on the night of February 2, 1959 in the northern Ural Mountains. The name Dyatlov Pass refers to the name of the group's leader, Igor Dyatlov.
The incident involved a group of nine experienced ski hikers from the Ural Polytechnical Institute (Уральский политехнический институт, УПИ) who had set up camp for the night on the slopes of Kholat Syakhl. Investigators later determined that the skiers had torn their tents from the inside out. They fled the campsite, probably to escape an imminent threat. Some of them were barefoot, under heavy snowfall. The bodies showed signs of struggle; Dyatlov had injuries to his right fist, as if he had been in a fist fight. One victim had a fractured skull and another was found with brain damage without any sign of distress to the skull. One of the skull fractures was so severe it was determined that he would not have been able to move. Additionally, one woman's tongue was missing. Soviet authorities determined that an "unknown compelling force" had caused the deaths; access to the region was consequently blocked for hikers and adventurers for three years after the incident. Due to the lack of survivors, the chronology of events remains uncertain, although several possible explanations have been put forward, including an avalanche, a military accident[citation needed], and a hostile encounter with a yeti or other unknown creature.
