The most voluminous Holocene lava flow on the southern flank of Medicine Lake volcano is known as the Burnt Lava flow.  The flow, which originated from High Hole Crater and nearby fissure vents, covers 37 sq km.  The flow is dominantly aa lava, but also includes some pahoehoe.  This photo shows the NW margin of the flow, which was erupted about 2750 years ago. Photo by Lee Siebert, 1998 (Smithsonian Institution).
