Restoration and coloriяation of a photos from the expedition, a few days before the disaster.

The Dyatlov Pass incident refers to the mysterious unsolved deaths of nine ski hikers in the northern Ural Mountains on February 2, 1959. The experienced trekking group, who were all from the Ural Polytechnical Institute, had established a camp on the slopes of Kholat Syakhl when disaster struck. During the night something made them tear their way out of their tents from the inside and flee the campsite inadequately dressed in heavy snowfall and sub-zero temperatures.
