Dyatlov Pass Incident Remains Earth's Most Terrifying Unsolved Hiking Puzzle

In 2021, Swiss researchers shed light on the tragedy, suggesting a delayed avalanche was the culprit.

A 1959 winter expedition in the Ural Mountains for a group of Soviet hikers turned deadly. Nine young adventurers, led by Igor Dyatlov, perished under a shroud of mystery. Scattered near their abandoned tent, some lay barefoot, others were strangely stripped, and a few even bore traces of radioactivity. Dyatlov, a radio engineering student, was found lying down in the snow, his clenched fists and open jacket hinting at a chilling struggle. Even after six decades, the cause remains unknown, leaving investigators haunted by unanswered questions in the unforgiving embrace of the frozen landscape.

According to The Metro, the group had ventured into the Urals, a mountain range that splits western Russia from Siberia, on a planned 16-day cross-country ski trip. Where the bodies were found has many names. To Soviet officials, the skiers' tent sat on the remote mountain, Height 1079. The Mansi, an indigenous people in the area, knew it as Kholat Syakhl, or Dead Mountain in their language. These days, the area is called the Dyatlov Pass, named after Igor.
