Its pretty straight forward. If it’s not a state or county road it’s closed unless designated open. There aren’t very many roads that are designated open. They will be signed open. If you don’t know, don’t go! That’s always the adage that will keep you out of trouble.
There are plenty of examples of open BLM tracks that cross small pieces of state land which are technically closed, and therefore, means landlocked public land because you can't take the road to get there (forget the walking for now).
There are no shortage of state trust roads that are closed, but join up with BuRec roads that are open.
There are plenty of two tracks that are closed, but are freaking highways considering the amount of traffic out on them illegally.
So while it may be clear as gin in your mind, the reality is telling us very different things that, a simple data layer available to all states would help fix.
It's a system that is opposite of the other public land agencies, therefore automatically creating more confusion. it's a system that the lessees really don't want to change because they're still not happy that hunters got the right to use those lands 25 years ago.
it's a system that's set up to generate revenue from leasing, not recreation. Hunting on state lands is still pretty darned new (25 years is all in MT) and the systems relative to their management have not kept up.
