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. The two thin black streaks in front of the Devils Homestead flow are 3000-year-old lava flows from fissures at Black Crater and Ross Chimneys.
