Subtitled: the Untold True Story of the Dyatlov Pass Incident
Nonfiction by Donnie Eichar
I had not heard of the Dyatlov Pass Incident before reading this book. Here's an overview:
In February 1959, a group of nine experienced hikers in the Russian Ural Mountains died mysteriously on an elevation known as Dead Mountain. Eerie aspects of the incident—unexplained violent injuries, signs that they cut open and fled the tent without proper clothing or shoes, a strange final photograph taken by one of the hikers, and elevated levels of radiation found on some of their clothes—have led to decades of speculation over what really happened.
This book is by a documentary filmmaker who researched the incident, and it is written in an interesting past-and-present format. And he actually comes up with an explanation at the end that makes sense.
