In February 1959, nine experienced Soviet hikers disappeared while crossing the northern Ural Mountains. Weeks later, searchers discovered their abandoned tent partially buried on the slope of Kholat Syakhl. Their boots, warm clothing, food and equipment were still inside—but the tent had been cut open from within.

The hikers’ bodies were eventually found scattered between the campsite and a forest nearly a mile away. Some had died from hypothermia. Others suffered catastrophic chest and skull injuries. Two were missing their eyes, one was missing her tongue, and traces of radioactive contamination were detected on several pieces of clothing.

For decades, the Dyatlov Pass incident has inspired theories involving secret Soviet military tests, UFOs, infrasound, katabatic winds, murder and even a Yeti. More recent investigations point toward a delayed slab avalanche followed by extreme weather, injury and disorientation—but does that theory explain everything?

In this episode of Kat Has Questions, Kat examines the hikers’ final photographs and diaries, the abandoned tent, the autopsy findings, the original Soviet investigation and the scientific theory that may finally explain what happened on Dyatlov Pass.
