Hoodoo Mountain still retains a four-kilometre thick ice cap on its flat summit that is separated into two glaciers. Mountain (climbing) weather forecasts for 2 elevations of Hoodoo Butte, Cascade Range, Pacific Coast Ranges, United States. The blocky lava flows still maintain their original forms.Hoodoo Mountain is a tuya in northwestern British Columbia, which has had several periods of subglacial eruptions. The oldest eruptions occurred about 100,000 years ago and the most recent about 7000 years ago. Volcanoes of the World (VOTW) - Hoodoo Mountain (320080) Citation. Mineral ization Mineralization on the Hoodoo claims is found within fault related, lenticular zones of silicification and brecciation accompanied by variable development of pyrite and sericite. A second example of ice-marginal lava flows can again be found in British Columbia, this time near the border of Alaska. Detailed 6 day mountain weather forecasts for climbers and mountaineers planning expeditions. Three of these zones Hoodoo Mountain volcano (HMV) is a Quaternary phonolitic volcano situated on the north side of the Iskut River, in the Coast Mountains of northwestern British Columbia, Canada. The Hoodoo Mountain Volcano is located in Northwestern British Columbia The volcano formed underneath a glacier, making it a subglacial formation. basalt eruptions can still be seen on the northern flank of Hoodoo Mountain.

Studies have shown that a cycle occurs about every 24,000 years, after which activity shifts from subglacial to post-glacial eruptions and then back to subglacial again. Its activity spans the last 100,000 years, it may have erupted as recently as 9 ka, and it encompasses a volume of approximately 17 km3. Height: 1,850 metres Location: 56.78°N / -131.28°W About: Located north of the Iskut River in the Coast Mountains, Hoodoo Mountain remains one of the best examples of a subglacial volcano.Subglacial volcanoes form underneath a glacier and normally remain inaccessible. Hoodoo Mountain is a well-exposed example of peralkaline, phonolitic ice-contact and subglacial volcanism. Hoodoo Mountain volcano, which is approximately 17 cubic kilometers in volume, erupts dominantly trachyte-phonolite composition lavas, although it also has closely associated basaltic centers.
