Mount Silverthrone is perhaps one of the most heavily glaciated volcanic peaks in southwestern British Columbia. It has a topographic prominence of approximately , greater than any other volcano in southwestern British Columbia. The extensive icefields around Mount Silverthrone are receding and are small compared to their former extent, but they are an impressive indication of how much of British Columbia looked 10,000 years or more ago. Silverthrone contains one of the few calderas buried beneath the ice caps of western Canada, another example being Mount Edziza in far northwestern British Columbia.
