The Dyatlov Pass Incident is a true mystery. Something happen in 1959 to a group of skiers in the Ural Mountains that defies any kind of easy explanation. All 9 were found dead, after fleeing their tent that night, slashing their way out, with no supplies and unprepared for the excessive cold outside. They were experienced at this type of camping, and why they would do this is beyond puzzling. They all died of hypothermia, some with even more puzzling injuries. So what happened to them? Keith McCloskey does a fantastic job in laying out their final days. He paints a picture of the Soviet Union at that time, and their trip up the mountain. You get a feel for who these people were and the environment they were living in. He then gets down to describing how they were found, and the condition and location of the bodies. It’s a hard to put down book. Keith attempts to give ample voice to the various theories and take things apart to examine the facts thoroughly. At no point does he claim to have a complete solution, nor does he ignore evidence. He presents what we know, how we know it, and possibilities. He does have his own thoughts on the matter, of course, which he expresses, but not in a way that feels like he is stating the definitive last word by any means. If you are new to this mystery or not, this is the book you want to read. Unnerving, fascinating, and just an overall good read. Highly recommended.
