High Hole Crater, a cinder cone on the SE flank of Medicine Lake volcano, was the source of a large, youthful-looking lava flow that was erupted about 2700 years ago. The lava flow, the largest from Medicine Lake during the Holocene, covered 37 sq km and had a volume of 0.45 cu km. Another even larger recent flow from Giant Crater on the south flank produced a lava flow that traveled 45 km to the south, well beyond the flanks of the volcano, about 10,600 years ago.
