Pisgah Crater, Volcanic cinder cone in San Bernardino County, California.

Pisgah Crater is a volcanic cone in the Mojave Desert of San Bernardino County, California. Black lava fields spread from the summit into the flat desert landscape, forming a dark band of solidified rock.

Pisgah Crater was mined as the Mount Pisgah Volcanic Cinders Mine, producing pumice mainly for Santa Fe Railroad ballast. Mining removed the summit and scoured the once-symmetrical cone into an irregular shape. The mountain is now owned by Can-Cal Resources Limited, a Canadian company exploring precious minerals in California, and quarrying occasionally continues.

University geology classes and professional groups conduct regular field studies at the crater, examining volcanic formations and mineral compositions.

The crater and much of the surrounding lava field lie on private property owned by Can-Cal Resources Limited, so access is not guaranteed. The lava tubes, including the 1,300-foot SPJ Cave, are nonetheless a somewhat popular caving destination. Quarrying still occurs occasionally, and the terrain is loose cinder and basalt.

Sand from Pisgah Crater was used to depict the black sands of Iwo Jima in Clint Eastwood's film Letters from Iwo Jima. The cone also holds SPJ Cave, a lava tube about 1,300 feet long that cavers visit.
