Stumbled on this by just exploring the backroads near the BLM campground down the road. Technically this is USDA Forest Service land, but it is RIGHT next to BLM land. 

Being dispersed, they are primitive sites. You're going to find man-made stone fire pits but that's about it. There are a handful of dispersed sites in this area. We found one nestled right next to the creek. It was great, very peaceful for the most part, except for when you can hear people on their ATVs or dirt bikes tearing around the area. Since this is so close to a BLM recreation site, expect to hear those activities.

Some of these sites can be tricky to get to unless you have a good vehicle for it. I was renting a 4Runner at the time so no issues, but I don't think I would have been able to get to the further in dispersed sites if I was driving a Civic.

All in all, really great spots right next to the old town of Liberty, and worth the $0 you'll spend to camp here. Hell, maybe even worth more, not that you'll have to worry about that.
