AbstractThe mass of snow deposited by individual avalanches at 46 sites at Rogers Pass, Canada, was measured during five years. A limit avalanche was determined for each site from the 30-year maximum snowfall, type of ground surface, and the area of the catchment. The mass of an avalanche with a 10-year return period was determined by fitting an extreme value frequency distribution. It was found that the mass of a 10-year maximum avalanche is a function of the limit avalanche and and the size of the catchment in a broad sense only, but not of other terrain parameters such as slope angles and exposure.
