The Dyatlov Group was a team of nine experienced hikers from the Ural Polytechnic Institute in the Soviet Union. In February 1959, they embarked on a skiing expedition in the Ural Mountains but tragically never returned. Their bodies were discovered weeks later, leading to widespread speculation about the cause of their deaths. The circumstances surrounding the incident remain mysterious, with various theories proposed, including an avalanche, military tests, or even paranormal activity. The case has since become a topic of intrigue, inspiring books, documentaries, and discussions about the Ural Mountains and the challenges of wilderness exploration.
