Who runs this map
This is a statewide map, not a county site. Montana Cadastral (Montana State Library) covers parcels across Montana, and Liberty County is one part of it. 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.
