The steep margin of a lava flow from a scoria cone at the northern end of Davis Lake is skirted by a road in Deschutes National Forest. This and two other nearby lava flows mark the Holocene eruptive activity in the Cascades between Mount Bachelor and Crater Lake.

The northernmost of the three Davis Lake lava flows, each associated with a scoria cone, originated from the forested cone in the background. The lava flow spread across a broad area, creating a natural barrier that formed Davis Lake about 5,050-5,600 years ago.

Three small scoria cones oriented along a N-S line produced large andesite lava flows. The northernmost flow formed the natural dam that created Davis Lake (right) and the two other flows are located behind Hamner Butte in the background. The middle flow has been radiocarbon dated to about 5,050-5,600 years old; the other two are considered to have erupted at around the same time and are possibly surface manifestations of the same dike.

The middle of three scoria cones with associated andesite lava flows near Davis Lake is seen here from Black Rock Butte, which is the southernmost cone, with the Pleistocene Hamner Butte shield volcano in the background. The middle lava flow has an age of 5,050-5,600 years. The vent that produced the middle flow has a flat summit that has been quarried for road aggregate.

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.

The middle of three andesite lava flows that erupted from three vents near Davis Lake has been radiocarbon dated at 5,050-5,600 years. The Pleistocene Odell Butte shield volcano is in the background, and the southernmost of the three lava flows can be seen in the distance below its left flank.
