From Wikipedia
The Salton Buttes are a group of volcanoes in Southern California, on the Salton Sea. They consist of a 7-kilometer-long (4.3 mi) row of five lava domes, named Mullet Island, North Red Hill, Obsidian Butte, Rock Hill, and South Red Hill. They are closely associated with a fumarolic field and a geothermal field, and there is evidence of buried volcanoes underground. In pre-modern times, Obsidian Butte was an important regional source of obsidian.
