The Medicine Lake lava flow, seen here from the NW with Medicine Lake in the background, was erupted onto the caldera floor from a vent near the northern caldera rim. The flat-lying, viscous 0.08 km3 lava flow is not precisely dated, but is known from stratigraphic evidence to have been emplaced sometime between the roughly 780 BCE Burnt Lava flow and the roughly 720 CE Hoffman flow.
