Dead Mountain: Why Nine Hikers Cut Their Way Out of Their Tent and Ran Into the Night

They set out laughing. The photographs later recovered from their cameras show ten young people in high spirits, mugging for the lens in the snow, loading a truck, clowning on the train north - a student ski expedition like a hundred others in the Soviet Union of 1959. Only one of them would come home. In late January, ten students and graduates of the Ural Polytechnical Institute in Sverdlovsk set out on a punishing Category III winter trek through the northern Urals, the hardest grade the Soviet system recognised, bound for a peak called Otorten. One of them, Yuri Yudin, fell ill early with rheumatic pain and turned back - the accident of health that would let him bury his friends decades later, and outlive the mystery until his death in 2013. He was the last to see the other nine alive.

Those nine were not amateurs. Their leader, twenty-three-year-old Igor Dyatlov, was a gifted radio engineer who built his own gear. Around him were Zinaida Kolmogorova and Lyudmila Dubinina, both seasoned and well-liked; Yuri Doroshenko, Rustem Slobodin, Georgy Krivonischenko, Alexander Kolevatov, and Nikolai Thibeaux-Brignolle, descendant of a French engineer. The odd figure was Semyon Zolotaryov, at thirty-seven a decorated war veteran and a late addition, older than the rest by more than a decade - a detail that would feed a hundred suspicions. On the night of 1 February they pitched their single long tent high on the exposed slope of Kholat Syakhl instead of descending to the tree line a mile below. The name, from the local Mansi language, is usually rendered as "Dead Mountain."
