Wide open dispersed desert camping. FS-558 runs for several miles south of HWY-285. We stayed closer to the highway which is safer without 4WD. Higher clearance is helpful due to ruts in the road. There's a fair amount of trash, but plenty of spots without. Bummer that locals use public land as their private dumping area. The nights were quiet, other than occasionally coyote calls, which add to the ambiance. We had a few thousand acres all to ourselves for four nights while climbing on nearby El Rito walls.
