In 1959, a group of hikers were found horribly mutilated and killed in a part of Russia's Ural Mountains. Until this day who murdered them remains a mystery, and since then other persons have died or disappeared there.
Dyatlov Pass is one of the most impassable regions of the Urals. Even the name of the region is shrouded in mystery and death. After the disappearance in 1959 of Igor Dyatlov and the hiking group he led, it has been known by this name.
