Coquihalla Mountain is an extinct stratovolcano in Similkameen Country, southwestern British Columbia, Canada, located {{Convert|10|km|mi|abbr=on}} south of Falls Lake and {{Convert|22|km|mi|abbr=on}} west of Tulameen between the Coquihalla and Tulameen rivers. With a topographic prominence of {{Convert|816|m|ft|abbr=on}}, it towers above adjacent mountain ridges. It is the highest mountain in the Bedded Range of the northern Canadian Cascades with an elevation of {{Convert|2157|m|ft|abbr=on}} and lies near the physiographic boundaries with the Coast Mountains on the west and the Interior Plateau on the east.
Geology
Coquihalla Mountain is a major preserved feature in the Miocene age Pemberton Volcanic Belt that was erupting about 21 to 22 million years ago.[http://www.gsajournals.org/perlserv/?request=get-document&doi=10.1130%2FGES00020.1 Cenozoic to Recent plate configurations in the Pacific Basin: Ridge subduction and slab window magmatism in western North America][https://www.for.gov.bc.ca/hfd/library/ffip/Monger_JWH1994_pt7.pdf Character of volcanism, volcanic hazards, and risk, northern end of the Cascade magmatic arc, British Columbia and Washington State] Like the Pemberton Volcanic Belt, Coquihalla Mountain formed as result of Cascadia subduction.
