Avalanches occur when a large amount of snow and ice or rock falls suddenly down a mountainside. There are slab (or wet) avalanches and powder snow (or dry) avalanches. They usually happen after storms and are caused by weak layers of snow being unable to support the weight of the snow above it and the overlying snow cracks and breaks away.

Avalanches occur in the back country where we like to play. Most avalanches occur on slopes between 35 & 45 degrees. Slopes less than 30 degrees rarely produce avalanches, and slopes greater than about 50 degrees tend to sluff off the snow often, and not build up slabs, not to say they will never avalanche down.
