Black Tusk volcanic remnant, Garibaldi Provincial Park, British Columbia, Canada.

Black Tusk (2319 meters or 7608 feet elevation) is an eye-catching pinnacle of volcanic rock in Garibaldi Provincial Park of British Columbia, in the Coast Range, Canada. Visible from the Whistler area, Black Tusk is part of Garibaldi Volcanic Belt within the Cascade Volcanic Arc (but is not within the geographic boundary of the Cascade Range, which is south of the Fraser River). Black Tusk is the remnant of an extinct andesitic stratovolcano which formed 1.3 to 1.1 million years ago as the Juan de Fuca, Gorda, and Explorer plates plunged under the North American Plate at the ongoing Cascadia subduction zone.
