The southernmost of three blocky andesitic lava flows near Davis Lake originated from Black Rock Butte and banks up against the slopes of the Pleistocene andesitic shield volcano Odell Butte.  The lava flow is considered to have erupted at about the same time as a nearby lava flow with a radiocarbon age of 4740 years. Photo by Lee Siebert, 1995 (Smithsonian Institution).
