The 70-sq-km Amboy lava field in southern California is composed mostly of vesicular pahoehoe lava flows that form a hummocky terrain with a surface relief of 2-5 m. Lava tubes are not present in the Amboy flows, which display abundant tumuli and pressure ridges. Light-colored deposits of aeolian sand, thicker to thw SW, fill depressions in the lava flow.

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.

Amboy Crater is a complex cone formed of at least four nested craters. The rims of two relatively undissected inner cones can be seen in this view from the SE rim of the outer crater of the 75-m-high cinder cone. The two outer cones are breached on their western sides, out of view to the left. Amboy crater is surrounded by a 70-sq-km basaltic lava field. The Bristol Mountains form the skyline.

Amboy Crater is a composite cinder cone that contains at least four nested craters. The two outermost craters are breached to the west. A broad lava field that extends from the cone is visible beyond the breach. Light-colored windblown sand deposited by prevailing winds from the west fill in low spots on the surface of the lava flow.
