Where the parcel data comes from
This is a statewide map, not a county site. Montana Cadastral (Montana State Library) covers parcels across Montana, and Rosebud County is one part of it. Because a state agency compiles this layer from local data, check with the Rosebud County assessor or recorder before relying on a recent change. Our October 2026 check found the map open to the public, with no account or payment needed.

Before you rely on the lines
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
