About the official source
This is a statewide map, not a county site. NM Office of the State Engineer County Parcels 2025 layer (ArcGIS Map Viewer) covers parcels across New Mexico, and Harding 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. Our October 2026 check found the map open to the public, with no account or payment needed.
