A steep-sided, blocky andesitic lava flow from a cinder cone at the north end of Davis Lake is skirted by a road in Deschutes National Forest.  This and two other nearby lava flows mark the only known Holocene eruptive activity in the Cascades between Mount Bachelor and Crater Lake. Photo by Lee Siebert, 1982 (Smithsonian Institution).
