Forested cinder cones of the Eagle Lake volcanic field rise above the SW shore of Eagle Lake. The volcanic field occupies the junction of the Cascades, Sierra Nevada, and Basin and Range geologic provinces. The Eagle Lake field consists of 15 cinder cones and basaltic lava flow vents within a larger Quaternary basaltic field. The vents are aligned along faults defining the Eagle Lake volcano-tectonic depression. The latest eruptive period occurred during the late-Pleistocene or early Holocene.
