Where the parcel data comes from
The link goes to a statewide map (Montana Cadastral (Montana State Library)). It shows parcels for Chouteau County along with the rest of Montana. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. When we tested the link in October 2026 it opened with no login and no fee.
