Hunting for the latest Sublette County plat book? It's a printed atlas of landownership, usually by township, and it's handy for land around Bondurant. This county guide covers: what's in a plat book, where to find editions, and the free online map that stays current around Boulder.
Tracking down a Sublette County plat book
In and around Pinedale, a plat book is a privately published atlas, that map ownership across the countryside, page by page across the county.
The viewer Sublette County publishes
Go first to the Sublette County parcel viewer; it covers each assessed parcel in the county, Bondurant included. If you only know roughly where the land is, zoom in from Pinedale and select the outline. For acreage around Cora, save the parcel ID while you have it open; every office in the county will want it.
Offices that can help
Deeds, mortgages and recorded plats for land near Pinedale are with the County Clerk, often with an online index. Questions about what you can build around Marbleton need the planning or permitting office, and the answer depends on jurisdiction.
Finding a printed edition
Editions come and go depending on publishers, so ask at the courthouse, extension office or a local library near Bondurant.
Reading the legal description
Wyoming is laid out under the Public Land Survey System, which means a tract near Cora is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Teton National Forest odd-sized. Write down the legal description for the tract near Bondurant for any title or survey request.
Deeds, plats and who keeps them
For a parcel near Teton National Forest, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are kept by the County Clerk. Inherited tracts near Cora can go back through several deeds, so a title company is worth hiring if money is changing hands.
Current ownership online
You can search by owner name or click a tract near Cora, then print or screenshot it.
Two kinds of plat
If you're looking near Bridger National Forest, a plat book is not a recorded plat: the recorded plat at the County Clerk is a legal document, and the atlas is just a guide.
Common uses
Farmers, hunters and appraisers near Daniel use plat books to see ownership across many tracts at once.
A word on accuracy
For land near Shoshone National Forest, the acreage figure is a tax-roll number; just a licensed surveyor sets the real corners on the ground. For a parcel near Calpet, records update in batches, so a deed recorded last month may not show yet.
Land on the county line
Sublette County borders Fremont County, Lincoln County, Sweetwater County, and Teton County, and each of those keeps its own parcel map. Ground near Bridger National Forest that runs to the line may show up in two county records, so open the adjacent map before you assume the acreage. Closer to Bondurant, the Platbookmapper state page lists every bordering county map for Wyoming.

Pinedale holds the county offices, home to the main records offices. You'll also find Big Piney, Marbleton, Bondurant, and Boulder, each with its own cluster of lots. Roughly 8,969 people live in Sublette County (Census estimate, 2023) on about 4,886 square miles. Sublette County was organized in 1921, so old deeds can run back a long way. Places such as Bridger National Forest make handy reference points on the map.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Marbleton, though signal can drop in rural spots. A printout of the tract near Shoshone National Forest keeps working without signal.
