Looking for a Prairie County plat book? These atlases map who owns rural land, page by page, and it's handy for land around Zero. This Prairie County guide covers: what's in a plat book, where to look for printed copies, and the free online map that stays current.
The Prairie County plat book: start here
If the land is near Terry, a plat book is a privately published atlas, with owner names on each tract, often organized by township.
Getting to the right map
Parcels around Mildred are published on the Montana Cadastral, free to use and open without a login. On ground around Zero, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Saugus, save the parcel ID from that panel; every clerk in the county uses it to find the file.
Deeds, plats and who keeps them
When the details count, request the recorded deed from the County Clerk and Recorder; the parcel map near Terry only summarizes it. Older tracts near Terry can sit on a long string of deeds, so a title company is worth hiring before a purchase.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Terry, so load it before you lose signal. A screenshot of the parcel near Fallon with its ID keeps working without signal.
Legal descriptions in Montana
Montana is laid out under the Public Land Survey System, so deeds around Terry reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Zero vary in size. Write down the legal description for the tract near Terry when you talk to a surveyor.
Neighboring parcel maps
The county borders Custer County, Dawson County, Fallon County, Garfield County, and McCone County, and each of those keeps its own parcel map. A tract near the line by Zero may be split in two county records, so check the neighboring map too. Near Terry, the Platbookmapper state page links every bordering county map for Montana.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor sets the real corners for a parcel near Terry. Near Saugus, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Where to look for one
Libraries near Mildred sometimes keep past atlases, which helps when tracing a farm's history.
Who handles what
Questions about value or the owner field for land near Mildred belong with the Montana Department of Revenue, the office behind the parcel record. Questions about what you can build around Terry are for the local planning and health departments, and the answer depends on jurisdiction.

Atlas or legal document
