I don’t know if it is exactly like homesteading. The land we own was homesteaded, the first entry on the deed is US Government to [homesteader].
I think grazing rights are more like a legal easement, the right to use the land for grazing purposes. The people that held preemptive rights or grazing rights never got a actual deed to the land. If they had got the actual deed like homesteaders did, Bundy’s wouldn’t be having the problems they are having now.
I didn't mean to imply it was an actual deed, but more that its a provision TO the deed, or as you said, an easement.
