4 Web Sites to Learn About Avalanches
From PBS – NOVA Online: “An avalanche, or slide, is simply a mass of snow moving down a slope. There are two basic elements to a slide; a steep, snow-covered slope and a trigger. But despite this apparent simplicity, avalanches can be surprisingly hard to predict. Changing weather conditions continually affect the strength of the layers within the snowpack, and the snowpack on every slope is different depending on what exposure that slope has to the wind and sun.”
