Abstract: Though avalanche workers and scientists recognize that distinct patterns of snow stability exist in mountainous terrain, no field-based research has been conducted to rigorously analyze those patterns at a scale of interest to backcountry avalanche forecasters. This research investigates snow stability throughout a small mountain range. Using helicopter access, sampling teams collected data from over 70 sites on each of two sampling days. Variables generated were analyzed using a variety of statistical techniques. Results demonstrate that links exist between terrain and stability, and that those relationships change over time. The data structure is complex, providing insights into the myriad difficulties faced by avalanche forecasters.
