Kohala is the oldest of the subaerial volcanoes that make the Island Of Hawaii. Kohala is considered to be extinct because it has not erupted for 60,000 years. Deep canyons have been eroded on the north flank of the volcano. A northwest trending graben along the crest of the volcano is marked by cinder cones and domes. Photograph by T.J.
