Which type of terrain poses a risk of avalanche?

Mountain areas are inherently more prone to avalanches due to their steep slopes and the presence of snowpack that can become unstable under certain conditions. These regions often have varying elevations, which contribute to different weather patterns that affect snowfall and melting processes. When fresh snow accumulates on a steep slope, it creates the potential for an avalanche if the underlying layers of snow are unstable or if additional weight is added from further snow accumulation or rapid changes in temperature.

The characteristics of mountainous terrain — including the angle of slopes, the typical accumulation of snow, and the interactions of weather — create a unique environment for avalanche occurrence. Unlike the other environments listed, such as lakes, rivers, open fields, and forests, which do not support the same conditions for avalanche formation, mountain areas present a significant risk that snowmobilers and outdoor enthusiasts must be aware of and prepared for. This understanding is crucial for safety and risk management when traveling in these regions.
