Mountain of the Dead

The Dyatlov Pass Incident
On February 2nd, 1959, during the cold winter on Kholat Syakhl ("Mountain of the Dead") in Russia, nine intrepid ski hikers decided to do what they do best, which is ski hike, whatever the hell that is. On February 26th, the first of their very dead bodies turned up. Man, who would have thought such a tragedy could strike on "The Mountain of the Dead?"

So there's six things that freak people out about this one:
1. The no-tongued woman
2. A mysterious orange tan on the dead bodies
3. The ripped tents
4. The hikers' lack of clothing
5. The crushing damage done to three of the hikers
6. The traces of radioactivity
