These are blm campsites. There are pit toilets right when you cross into blm land and a sign that explains that you have to camp in designated areas. Like most blm locations there is a 14 day max.

We got our 19 foot travel trailer into a spot with icy conditions, but the road does get quite a bit rougher if you keep going in. Great T-Mobile and Verizon service (2+ bars of 5g)
