Davis Lake volcanic field, Cinder cone field in Oregon, US.

Davis Lake volcanic field lies just east of the Cascade Range crest in Oregon and consists of three young andesitic cinder cones with their associated lava flows. The northernmost flow blocked Odell Creek, and the water backed up behind it formed Davis Lake.

The field's three andesitic cinder cones and their lava flows are young by geological standards; charcoal beneath the cinder deposits gives an age of 5,300 to 5,600 years for the latest eruptions. The northernmost flow dammed Odell Creek, creating Davis Lake.

The field takes its name from Davis Lake, which the northernmost andesitic lava flow created by damming Odell Creek. The three cinder cones and their lava flows sit just east of the Cascade Range crest, and the lake itself is the feature visitors most often notice first.

Access to this area is easiest through the nearby towns of Gilchrist and La Pine, where visitors can find information about the geology. The driest months offer the best conditions for exploring the volcanic landscape on foot.

The northernmost of the three andesitic lava flows blocked Odell Creek and created Davis Lake itself, so the lake is a direct product of the field's youngest-looking flow rather than a pre-existing basin. The cones and flows sit just east of the Cascade Range crest.
