Hoodoo Mountain

Hoodoo Mountain is a remote stratovolcano in northwestern British Columbia whose broad, nearly flat summit is capped by a thick ice mass, making it one of the most distinctive peaks in the Boundary Ranges. Much of the volcano formed beneath glacial ice, and glaciers or an ice cap have covered it for much of its history. Built mainly of phonolite and trachyte, it erupted in six periods beginning about 85,000 years ago, with its latest activity starting about 10,000 years ago and a possibly much younger lava flow on its southwestern side. Seismic activity since the mid-1980s indicates it is still potentially active and important for studying glaciovolcanic processes.
