Russia's Other Dyatlov Pass - Khamar Daban

In August 1993, a group of seven experienced Russian hikers set out into the Khamar Daban mountains of Siberia, led by one of the most respected wilderness guides in the country. Within minutes of beginning their descent, six of them were dead, dying with blood pouring from their faces and convulsions the official record can't explain. One 17-year-old survived, and she spent 25 years not talking about it. This is Siberia's other Dyatlov Pass, and the answer is still missing.
