Dyatlov Pass Mystery
21 December
In 1959 a group of Soviet students led by Igor Dyatlov went missing in the snowy Ural Mountains. Their bodies were found far from their tent, with unexplained injuries. A series of investigations have failed to unravel the mystery of what went on during the hiking trip. At the time the medical examiner said their deaths were due to hypothermia and their fatal injuries. But how they met their fate, no-one knows.
