Lava Beds National Monument is the site of the largest concentration of lava tube caves in the United States. The monument lies on the northeast flank of the Medicine Lake shield volcano, the largest volcano (total area covered) in the Cascade Range.
The region in and around the monument is unique because it lies on the junction of the Sierra-Klamath, Cascade, and Great Basin physiographic provinces. In addition, the monument is geologically outstanding because of its great variety of “textbook” volcanic formations; i.e., lava tube caves, fumaroles, cinder cones, spatter cones, maar volcanoes, and lava flows.
Some of the major Lava Flows within Lava Beds National Monument include: Callahan Flow, Schonchin Flow, Mammoth Crater Flow, Modoc Crater Flow, and Devils Homestead Flow.
Visitors can tour both the geologic and historic wonders of this unusual landscape.
