An excerpt from the article 39 facts about Dyatlov Pass incident

Dyatlov was an experienced tourist belonging to the Ural Polytechnical Tourism Section. He had repeatedly participated in summer and winter mountain expeditions, and two years before the tragedy in the Pass, he had ventured into the Ural Mountains. The issue of him winning the "Master of Sports in Tourism" decoration was his greatest ambition and a sign of prestige. Researchers have concluded that of all the participants in the expedition, Igor was the one who took it deadly seriously, which meant he could display bravado and impose an inhuman walking pace. It could also mean that he consciously gave up taking the radio station, which would have been an additional burden.
