Hoodoo Mountain is located north of the Iskut River in the Coast Mountains of northwestern British Columbia, Canada. The volcano formed under glacial ice, and a 3-4 km wide ice cap still covers the upper part above 1750 m elevation, forming 2 glaciers, the Hoodoo glacier on the northwest and Twin glacier on the northeast side. It has a circular shape with a basal diameter of 6 km and a flat top.
