The summit of Schonchin Butte in Lava Beds National Monument provides a view of step-like Basin-and-Range faulting to the NW. The dark lava flow at the base of the closest scarp is the late-Pleistocene Devils Homestead lava flow. Parallel to, and just in front, of that are 3,000-year-old lava flows from fissures at Black Crater and Ross Chimneys.
