Dyatlov Pass Incident: The Grotesque Death Of Nine

In February 1959, nine hikers, led by Igor Dyatlov, died in mysterious circumstances on the slopes of the Ural Mountains. Rescuers found their bodies hundreds of metres from the campsite. The tent had been slashed from the inside and still contained their clothes and shoes. Their half-naked corpses had crushed ribs, fractured skulls; one poor girl was even missing her tongue. An inquest at the time concluded that they had been killed by "unknown compelling natural force". Numerous conspiracy theories have since offered more outlandish explanations: from Soviet military tests to yetis and aliens. Sixty years on, the Dyatlov Pass incident is a cold case that still has investigators stumped.
