How to use the Washakie County plat book
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Worland the year it was printed. Deeds and recorded plats, not the atlas, still govern land near Big Trails in the county.
Search Washakie County parcels by owner, address or ID
The county's own public map is the Washakie County Beacon site, built on Schneider Geospatial's Beacon platform, and it opens without an account for parcels in Worland and the rest of the county. In the county version, the search page takes an owner, an address or a parcel ID, and each report links back to the map view for the tract close to Worland. For a backup route to the map covering Big Trails, our Washakie County directory entry keeps the link current.
Current and older editions
