Coquihalla Mountain is an extinct stratovolcano in Similkameen Country, southwestern British Columbia, Canada, located 10 km (6.2 mi) south of Falls Lake and 22 km (14 mi) west of Tulameen between the Coquihalla and Tulameen rivers.

It is the highest mountain in the Bedded Range of the northern Canadian Cascades with an elevation of 2,157 m (7,077 ft) and lies near the physiographic boundaries with the Coast Mountains on the west and the Interior Plateau on the east.

Coquihalla Mountain is a major preserved feature in the Miocene age Pemberton Volcanic Belt that was erupting about 21 to 22 million years ago.

[1][2] Like the Pemberton Volcanic Belt, Coquihalla Mountain formed as result of Cascadia subduction.
