The southernmost of three andesite lava flows near Davis Lake originated from Black Rock Butte and banks up against the slopes of the Pleistocene Odell Butte shield volcano. The lava flow is considered to have erupted at about the same time as a nearby lava flow with a radiocarbon age of 5,050-5,600 years.
