When a deed near Granger says lot and block, you'll need the Green River plat map to make sense of it. In this Green River guide: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
The Green River plat map: start here
For a subdivision near Granger, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Where the parcel data lives
Begin with the Sweetwater County parcel viewer; it covers every assessed parcel from Rock Springs to Wamsutter. If the land is near Bairoil, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Bairoil, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Green River, WY: the basics
Green River lies within Sweetwater County, Wyoming, and the county assessor maps its lots. As the county seat, Green River hosts the courthouse, handy when you need recorded documents. With a lot near Rock Springs, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits toward Granger usually answers to county rules instead.

Plat map vs. parcel map
Where lines don't match in Green River, trust the recorded documents over the GIS layer.
When a plat changes
Lots near Granger can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Wamsutter show up in the records too.
Sections, lots and bearings
Wyoming uses the Public Land Survey System, so rural legal descriptions near Bairoil cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Wamsutter vary in size. Keep the legal description for land near Rock Springs before you request a deed or survey.
When a parcel crosses a boundary
Sweetwater County touches Moffat County, CO, Daggett County, UT, Summit County, UT, Carbon County, and Fremont County, and each of those keeps its own parcel map. Ground near Granger that runs to the line can be split across two assessors' files, so look at the adjacent map before you assume the acreage. The Platbookmapper state page links each neighboring county map across Wyoming.

Online indexes and office visits

What the map can't tell you

Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Superior are filed with the County Clerk. Older tracts near Wamsutter may trace back through many deeds, so a title company earns its fee if money is changing hands.
