Ubehebe Crater is a large volcanic crater that is half a mile (one kilometer) wide, 500 to 777 feet (150 to 237 m) deep, and 4-7 thousand years old.

"Ubehebe" (pronounced YOU-bee-HEE-bee) is a Native American word meaning "Big basket in the rock." The crater was formed when magma migrated close to the surface and the heat of the magma flashed groundwater into steam, throwing large quantities of pulverized old rock and new magma at speeds of 100 to 200 mph (160 to 320 km/h) across the stony alluvial fan draped across the valley floor.
