Hoodoo Mountain

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges.
Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther to classify it as a tuya, and although it has experienced eruptions that interact with Pleistocene ice sheets, its complex layering of rocks separates it from subglacial volcanos. Cliffs occur on the summit and at the base of Hoodoo Mountain that reach an elevation between 328 and 656 feet. Its eastern, western, and northern sides are covered by the Hoodoo and Twin glaciers, both of which feed rivers of the same names, which in turn feed the Iskut River. A small tuya known as Little Bear Mountain can be found north of Hoodoo Mountain. Studies have shown that this volcano is actually a parasitic cone, which was created when an eruption from Hoodoo Mountain was blocked and forced to emit from the sides of the volcano.

Studies conducted at Hoodo Mountain have shown that it cycles through subglacial and post-glacial eruptions about every 24,000 years. These eruption phases have changed the landscape around the volcano over the past eighty thousand years, although its last eruption is not thought to have been explosive. Recent seismic activity from this volcano, and others in Canada, have shown evidence of magma chambers which could erupt in the future. The results of a possible eruption would be dangerous to the surrounding wildlife and highly damaging to mining operation located about ten miles away from the volcano.
