It has an elevation of Шаблон:Nowrap and a topographic prominence of Шаблон:Nowrap, making it the highest point on an east-trending screed ridge. This horn-like rocky tower is similar to The Black Tusk in Garibaldi Provincial Park.

Geology

Chipmunk Mountain is the remains of an extinct volcano that formed during the Miocene epoch.[1][2] The volcanic rocks comprising Chipmunk Mountain crop out in a Шаблон:Nowrap area and consist of pyroclastic rocks, sills and dikes. These volcanic rocks range from basalts to rhyolites, with the majority classifying as basaltic andesites and andesites. They are closely related to the calc-alkaline volcanic centres of the Pemberton Volcanic Belt, indicating that the volcanic rocks comprising Chipmunk Mountain were created as a result of volcanism in the Canadian Cascade Arc. The volcanic rocks have been dated to be Шаблон:Nowrap million years old, which correlates with the time of Pemberton Belt volcanism.[2]
