Who runs this map

Treasure County doesn't have its own viewer in our directory, so we point you to a statewide map: Montana Cadastral (Montana State Library). Zoom in on Treasure County to see its parcels. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. As of our October 2026 test, anyone could open it without signing in or paying.

How to use the Treasure County viewer

  1. Open the statewide map with the button above.
  2. Search for an address in Treasure County, or zoom to the county on the map.
  3. Click a parcel to see the attributes the state layer includes.
  4. Write down the parcel number and use it for records searches with the Treasure County assessor or recorder.

Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.
