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% were recreationists and of these, roughly 75% 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.
