Lavic Lake volcanic field

Its cones lie directly alongside historic Route 66 and modern Interstate 40, between Barstow to the west and Ludlow 10 miles (16 km) to the east.

[1] The 100 km2 (39 sq mi) Lavic Lake volcanic field is a basaltic pahoehoe lava plain and has four Holocene (approximately 10,000 years ago) cinder cone type volcanos, three in the Lavic Dry Lake area, and a fourth located southwest in the Rodman Mountains.

[1][2] The oldest cinder cone, Pisgah Crater may be pre-Holocene, erupting around 25,000 years ago.

The cone of Pisgah Crater has been modified by mining operations that provide a source of road aggregate.

[1] The biome is the deserts and xeric shrublands, with smaller plants growing in soil pockets formed by erosion, sedimentation and wind deposits.
