Amboy Crater is an isolated 75-m-high cinder cone seen here from the NW with the Bullion Mountains in the background. Amboy was the source of a 70-sq-km basaltic lava field that was erupted during the late Pleistocene onto a flat-lying alluvial valley. The dominantly pahoehoe lava field divided the Bristol Dry Lake into two playas. Depressions on the surface of the lava flow are filled with light-colored windblown sand distributed by prevailing winds from the west. The light-colored diagonal stripe on the flank of the cone is a trail leading to the crater rim.
