Pisgah Crater
Pisgah Crater, or Pisgah Volcano, is a young volcanic cinder cone rising above a lava plain in the Mojave Desert, between Barstow and Needles, California in San Bernardino County, California. The volcanic peak is around south of historic U.S. Route 66-National Old Trails Highway and of Interstate 40, and west of the town of Ludlow. The volcano had a historic elevation of , but has been reduced to due to mining.〔USGS Sunshine Peak 7.5'' topographic map, 1955〕
==History==
The volcano was the site of the Mount Pisgah Volcanic Cinders Mine, a cinder quarry that produced pumice for commercial use, the primary end product being railroad ballast for the Santa Fe Railroad. The mountain is currently owned by Can-Cal Resources Limited, a Canadian company specializing in exploration of precious minerals in California.〔(MinDat.org )〕〔(Pisgah 43-101 - Can-Cal Resources Ltd )〕
Mining has had a severe environmental impact; the top of the mountain has been removed and the sides of this historically symmertrical mountain have been scoured into an irregular shape. The mountain is still occasionally quarried for various cinder products, and sand from the mountain was used to depict the black sands of Iwo Jima in the film ''Letters from Iwo Jima''.〔(Letters from Iwo Jima - Filming Locations )〕
