There is an act which just passed the House of Representatives that will require the Federal land management agencies to enter their landownership and public access records in a GIS and make that available on their websites. It even appropriates some funding to make that happen. From the sponsor's website:
"Currently, more than 9.52 million acres of land in the West lack permanent and legal access points for public use, and information on these lands is still kept on paper files. Approximately 5,000 of the Forest Service’s 37,000 recorded easements have been digitized and uploaded to an electronic database. The MAPLand Act will help give federal land management agencies the resources they need to digitize these files for public use, as well as require these agencies to provide information on seasonal vehicle restrictions on public roads and trails, hunting boundaries, and watercraft restrictions."

So, by 2025, it might be easier to find out how you can access more public lands.
