It is called "The Dyatlov Pass incident" and was an event that resulted in the deaths of nine hikers in the northern Ural mountains on February 2, 1959. For some unknown reason the hikers tore open their tent from within and left barefoot in the snow, only the hikers footprints were found and there was no sign of a struggle.
They first found five bodies, a medical examination found no injuries which might have led to their deaths, and it was concluded that they had all died of hypothermia. One person had a small crack in his skull, but it was not thought to be a fatal wound.
The other four bodies were not found until May 4, an examination of the four bodies is where it starts to get really weird. Two of the corpses showed no signs of struggle but had fractured skulls, two had broken ribs, and one was missing her tongue. To add to the mystery, the four victims clothing contained high levels of radiation.
It was later stated that the three of them that had the fatal injuries was one had major skull damage, 2 had major chest fractures. The force required to cause such damage would have been extremely high, with one expert comparing it to the force of a car crash. The bodies had no external wounds, as if they were crippled by a high level of pressure and of course the woman who was found to be missing her tongue.
Journalists reporting on the available parts of the inquest files concluded that Six of the group members died of hypothermia and the other three of fatal injuries.
Now this is where the aliens were thrown into the mix. Another group of hikers reported that they saw strange orange spheres in the night sky on the night of the incident and toward where the incident took place. Similar "spheres" were observed in adjacent areas and continued during the period of February to March of 1959, by various independent witnesses (including the meteorology service and the military).
After the funerals, relatives of the deceased claimed that the skin of the victims had a strange orange tan. Other reports suggested that they found scrap metal in the area, leading to speculation that the military had utilized the area secretly and might be engaged in a cover-up. This has to be one of the weirdest things I have read to date. Click here for a detailed summary of the event >>>
