I planned to stay but severe storm was on the way. Drove through to at least check out. Free camping. Vault toilets. Water taps. Campground is on a bluff over Shadehill reservoir in national grassland. Most sites are pretty close together. I would have selected #11 if I had stayed.
It looks almost abandoned since you have to know it is here. Hard to impossible to find info on USDA web. I only knew about it from The Dyrt.
