4 stars for its genre. The author dissects a bizarre incident in which some Russian college kids were out camping in the Siberian wilderness and all 9 suddenly fled their tent without their coats or boots and died of hypothermia. A thoughtful dissection of the available evidence (more than 50 years old!) and review of the existing theories. Of course the author puts forth his own theory. I enjoyed reading this.

My one gripe, as someone with training as a scientist-- How you gonna put forth this wild theory and then do NOTHING to prove it??

Spoiler

At least set up some equipment to test whether the phenomenon really happens at that site. Or, if this is not possible for some reason, tell us why! This really bothered me, I feel like the story is not wrapped up at all. All he did was confer with some experts who felt like the SHAPE of the mountain from one picture was consistent with forming the right conditions. This does not satisfy me at all.
