Gaps with no tint inside public land are private parcels, often old mining claims and homesteads. They are not open to the public.
Dashed clay lines on the base map are unpaved tracks from OpenStreetMap. They show what exists on the ground, not what is legal to drive.

The map could not start in this browser.
It needs WebGL, which is turned off or unavailable here. You can still browse public land by state, or use the BLM’s own maps.
Boundaries are approximate and land status changes. This map is a planning aid, not a survey or a statement of access. Confirm routes, closures and camping rules with the managing office.
