The El Pinacante range of volcanic craters is 35 miles away to the north. Also Black Mtn is a Volcano cone across from Cholla Bay.
El Pinacante park is Pretty impressive to visit, black lava fields everywhere.
We drove in there on a Memorial day weekend years ago, the temp increased from 99 at highway 8 to over 120 degrees 5 miles in.
Our cars started to over heat so we had to turn off the A/C driving thru the sandy parts of the roads.
There's hundreds of cinder cones in there.
I don't think we need to worry about a eruption, they've been silent for a few thousand years, but with global warming you never know.
El Pinacante is currently closed to visitors, it requires a permit and guide to take you in now. Russ may know more about it.
I would go again but Nov-April.
