Free BLM dispersed camping with plenty of open flat areas with trees and bushes to allow for a sense of privacy to choose from. Saw a few other campers along the road but were able to easily find a private space for the night at 33.749426,-113.731680.
There were multiple spots with rock fire pits, some garbage but not horrible. Ground is very rocky so probably not good for tents. The road in is easy enough and fairly smooth and we made it easily quite a way back in our 26ft motorhome.
Some road noise in the distance and occasional plane but other than that a quiet night. No amenities so pack in and pack out and bring your own water.
Good cell reception with Verizon and AT&T.
