The Salton Buttes is a new one for me and I have lived in SoCal all my life except for the service.
I just checked it out. It is located at the Southern end of the Salton Sea. The have geothermal activity in the area which I new about. I just did not realize the area was a volcano.
Me too. I had heard about the Salton volcano. Have been to New Mexico’s cinder cones though.
