Who runs this map
The link goes to a statewide map (Montana Cadastral (Montana State Library)). It shows parcels for Teton County along with the rest of Montana. 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.

- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
