Ubehebe Crater is a maar volcano located off Scotty's Castle Road in Death Valley National Park, California. The colorful strata visible in the wall of the crater are sedementary deposits of the Navadu Formation. Ubehebe is the largest in a cluster of maar volcanoes located in this area. The explosions that formed these craters were caused by steam created when a small amount of basaltic magma encountered subsurface water.
