Snow Stability Tests are methods used by backcountry skiers and avalanche forecasters to assess the stability of snowpack layers. These tests help determine the likelihood of avalanches by examining how different layers of snow interact with each other. Common tests include the Compression Test and the Rutschblock Test, which measure how easily a slab of snow can be triggered to slide. Performing these tests involves digging a snow pit to analyze the layers and then applying force to see if a fracture occurs. The results provide valuable information about the snow's strength and help inform decisions about safe travel in mountainous areas during winter conditions.
