Dyatlov Pass Incident

In 1959, nine experienced hikers disappeared in Dyatlov Pass, Russia. Their camp was discovered with tents cut open from the inside and their bodies were found up to 2,000 feet away from camp. There were no signs of a struggle. Their injuries were quite peculiar: One victim had a fractured skull, another had brain damage but no physical signs of an injured skull and another had their eyes and tongue removed.

According to Dr. Boris Vozrozhdenny, the force required to cause such damage would have been extremely high, comparing it to the force of a car crash. Theories on what happened range from an animal attack, hypothermia, paranormal activity, a secret weapons test, and UFOs.
