Snow Sense Avalanche Book

A Guide to Evaluating Snow Avalanche Hazard - By Jill Fredstone and Doug Fesler. In the United States between 1950-51 and 1992-93, 420 people are known to have died in 310 separate snow avalanche incidents. Four out of five, or 80 percent were recreationists and of these, roughly 75 percent were travelling in the backcountry. A majority of the victims triggered the avalanches that killed them. This book addresses the critical terrain, snowpack, and weather variables that make it possible for a slide to occur along with the human factors that allow most accidents to happen.
