The Salton Buttes volcanic field is the youngest and southernmost of the fields associated with the North American and Pacific plate boundary. Five obsidian rhyolite domes erupted on the southern shore of the Salton Sea between 6000 and 500 years ago. The area is active geothermally and seismically, with numerous hot springs and mudpots on the surface.
