The andesitic Burnt Lava flow covering about 37 km² of the SE flank of Medicine Lake volcano was erupted from the High Hole Crater cinder cone. The Burnt Lava flow was the largest from Medicine Lake during the Holocene and had a volume of 0.45 cu km. The symmetrical High Hole Crater contains a double summit crater. The Burnt Lava flow, which was erupted from both High Hole Crater and adjacent fissures, surrounded two older cinder cones, one of which forms the forested ridge at the left.
