We found this cluster of percolating mudpots and mud volcanoes in a field at the intersection of two gravel roads near the southeastern corner of the Salton Sea. (Click on pics to make them bigger.)
The geothermal area sits on the southern end of the San Andreas fault atop a fumarole, an opening in the earth's crust that emits steam and gases such as carbon dioxide, methane and sulfur dioxide.

Getting there: Drive about three miles south of Niland on Highway 111 to Schrimpf Road and hang a right. Drive about three and a half miles until the intersection with Davis Road. Click on the map to make it larger.
