Amboy Crater is an extinct North American cinder cone type of volcano that rises above a 70-square-kilometer (27 sq mi) lava field in southern California. It is a National Natural Landmark located in the Eastern Mojave Desert and within Mojave Trails National Monument, in San Bernardino County, California.
It is equidistant and about 75 miles (120 km) between Barstow to the west and Needles to the east, and 1.5 miles (2.4 km) south of historic U.S. Route 66, near the town of Amboy, California in San Bernardino County, California. Amboy Crater was designated the Amboy Crater National Natural Landmark in May, 1973.
The Amboy Crater's location is 2.5 miles (4.0 km) southwest of the town of Amboy and the Route 66-National Trails Highway. The Bullion Mountains are to the west, and Bristol Mountains to the northeast.
This cinder cone is estimated to be 79,000 years old (+/- 5,000 years) and was formed in layers of mostly vesicular pahoehoe – during the geological period. The interior has a lava lake. Lava flows as old as Amboy Crater itself blanket the surrounding area. The most recent eruption was approximately 10,000 years ago.
