The Dyatlov Pass incident refers to the mysterious deaths of nine experienced hikers in the Ural Mountains of Russia in February 1959. Led by Igor Dyatlov, the group set out for a skiing expedition but never returned. Search parties later found their tent, which had been cut open from the inside, and the bodies scattered nearby, some with strange injuries. The circumstances surrounding their deaths remain unexplained, with theories ranging from an avalanche to military tests. Some hikers were found without adequate clothing, and others had unusual injuries, leading to speculation about possible encounters with wild animals or even extraterrestrial activity.
