On February 2, 1959 nine young students went hiking in the Ural Mountains of Russia, and never returned. The deaths of the nine hikers remains a phenomenal mystery to this day. Investigators found the abandoned tent ripped open from the inside, with all of the hiker’s belonging still inside. Five of the hikers were found frozen to death near the campsite; the bodies were found with nearly bare, suggesting the hikers ran from the tent in a terror, leaving behind shoes, jackets and other necessities to survive the mountain. There was no sign of a struggle. The last victims were found over 80 yards away from the campsite. These four bodies were found with strange injuries including internal damage, crushed skulls, and one was even missing her tongue. The clothes of these victims were found to have high levels of radiation.
Soviet investigators determined only that “a compelling unknown force” had caused the deaths.
