Cinder Cone is a cinder cone with a small crater on the west side of the Helm Glacier in Garibaldi Provincial Park in British Columbia, Canada. Cinder Cone is surrounded by cinder flats and its crater is filled with meltwater during the summer. Cinder Cone is eroded easily by meltwater during the spring, washing the pyroclastics into the Valley of Desolation. Cinder Cone produced a 9 km (6 mi) long lava flow during the early Holocene.
