The Dyatlov Pass Incident was an event that resulted in the deaths of nine hikers in the northern Ural Mountains on the night of February 2, 1959. The incident happened on the eastern side of Kholat Syakhl. Since then, the mountain pass where the incident occurred has been called Dyatlov Pass after the group's leader, Igor Dyatlov.
The 2015 Polish horror game Kholat is inspired by the Dead Mountain incident, in which the player goes to Dyatlov Pass in order to trace the steps of the lost expedition, and begins to uncover "the true cause" of the hikers' deaths.
Description[]
A group was formed for a ski trek across the northern Urals in Sverdlovsk Oblast. The original group, led by Igor Dyatlov, consisted of eight men and two women. Most were students or graduates of Ural Polytechnical Institute (Уральский политехнический институт, УПИ), now Ural Federal University.
The goal of the expedition was to reach Otorten (Отортен), a mountain 10 kilometres (6.2 mi) north of the site of the incident. This route, in February, was estimated as Category III, the most difficult. All members were experienced in long ski tours and mountain expeditions.
The group arrived by train at Ivdel (Ивдель), a city at the center of the northern province of Sverdlovsk Oblast on January 25. They then took a truck to Vizhai (Вижай) – the last inhabited settlement so far north. They started their march toward Otorten from Vizhai on January 27. The next day, one of the members, Yuri Yudin, was forced to go back due to illness. The remaining group of nine people continued the trek.
Diaries and cameras found around their last campsite made it possible to track the group's route up to the day preceding the incident. On January 31, the group arrived at the edge of a highland area and began to prepare for climbing. In a wooded valley they cached surplus food and equipment that would be used for the trip back. The following day (February 1), the hikers started to move through the pass. It seems they planned to get over the pass and make camp for the next night on the opposite side, but because of worsening weather conditions–snowstorms and decreasing visibility–they lost their direction and deviated west, up towards the top of Kholat Syakhl, a mountain whose name in Mansi means "Dead Mountain." When they realized their mistake, the group decided to stop and set up camp there on the slope of the mountain, rather than moving 1.5 kilometres (0.93 mi) downhill to a forested area which would have offered some shelter from the elements. Yudin, the lone survivor, postulated that "Dyatlov probably did not want to lose the altitude they had gained, or he decided to practice camping on the mountain slope."
