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.

The northernmost of the three Davis Lake lava flows originated from the forested cinder cone in the background. The blocky lava flow spread out over a broad area, creating a natural barrier that formed Davis Lake about 4740 years ago.

Three small cinder cones oriented along a N-S line produced large andesitic lava flows near Davis Lake. The northernmost flow formed the natural dam that created Davis Lake (right). Two other lava flows are located behind Hamner Butte in the background. The middle flow has been radiocarbon dated at about 4740 years ago, and the other two flows are considered to have been erupted at about the same time.

The middle of three cinder cones and flat-lying andesitic lava flows near Davis Lake is seen here from Black Rock Butte, the southernmost cinder cone, with the Pleistocene andesitic shield volcano of Hamner Butte in the background. The middle lava flow has a radiocarbon age of 4740 years. The cinder cone vent of the middle flow has a flat summit that has been quarried for road aggregate.

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.

The middle of three flat-lying andesitic lava flows erupted from vents near Davis Lake has been radiocarbon dated at 4740 years. The Pleistocene andesitic shield volcano Odell Butte is in the background, and the southernmost of the three lava flows can be seen in the distance below its left skyline.
