Go first to the Colorado Public Parcel Map; it covers every assessed parcel from Dolores to Mancos. For a home near Mancos, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Dolores, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
