Snow avalanches occur for very specific reasons and are part of the winter environment in every steep, snowy mountain range--including the Sierra Nevada. As backcountry riders we must have the skills to manage our risk in avalanche terrain. Most avalanches that injure or kill are triggered by those riding the slope.
Have your avalanche hazard assessment skills kept pace with your ability to access avalanche terrain? With proper education and training nearly all avalanche accidents can be avoided.
Donner Summit Avalanche Seminars are designed for backcountry skiers, snowboarders, and split boarders who seek adventure in the high mountains.
Donner Summit Avalanche Seminars will teach you how to:
EVALUATE the avalanche hazard regionally, locally, and for specific slopes
RECOGNIZE weather factors that create unstable snow
IDENTIFY weak snowpack layers that precede avalanches
MANAGE your risk while traveling through avalanche terrain
USE valuable tools and skills in avalanche rescue

"...while on a ski tour, I tried to steer the discussion away from intangibles, and keep to readily observable facts, and our group made the right call. As it turned out, another party triggered an avalanche. For the 14th time--thanks!"
