Cinder Mountain is a partly eroded cinder cone at the head of Snippaker Creek, British Columbia, Canada. It is one of the Iskut-Unuk River Cones and is the source of a basaltic lava flow that extends north into Copper King Creek. An isolated pile of subaerial basalt flows and associated pillow lava rest on varved clay and till in King Creek. Cinder Mountain last erupted during the Pleistocene.
