Ubehebe Crater

Hwy 190 ends at 600ft-deep Ubehebe Crater, formed some 300 years ago by the meeting of fiery magma and cool groundwater. As the water turned into steam, it expanded until the pressure gave way to a cataclysmic explosion. The result is easily appreciated from the parking lot, but you can also walk down to the bottom or loop around the perimeter of the half-mile-wide crater.
