The Wheatland County plat book: start here
Small lots in Duncan Ranch Colony or Shawmut are usually too small to label, which is where the parcel viewer helps.
Pulling up a parcel
Begin with the Montana Cadastral; it includes every tax parcel around Judith Gap and Springwater Colony. Out toward Twodot, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Duncan Ranch Colony, save the parcel ID from that panel; each office in the county uses it to find the file.
Deeds, plats and who keeps them
For a parcel near Shawmut, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are filed with the County Clerk and Recorder. Long-held tracts near Judith Gap can go back through many deeds, and a title company earns its fee on a real sale.

Which office to call

Editions and availability
Not every county has a current edition, so ask at the courthouse, extension office or a local library near Lewis and Clark National Forest.
Between editions

Common uses
Farmers, hunters and appraisers near Twodot use plat books for a big-picture view of who owns what.
Limits of the parcel data
For property near Lewis and Clark National Forest, listed acreage is an assessed number; only a licensed surveyor establishes the real boundary on the ground. For land near Twodot, records update in batches, so a deed recorded last month may not show yet.
Plat book vs. recorded plat
For a home near Lewis and Clark National Forest, a plat book is not a recorded plat: the recorded plat at the County Clerk and Recorder is a legal document, and the atlas is just a guide.
Legal descriptions in Montana
Montana is laid out under the Public Land Survey System, so deeds around Duncan Ranch Colony reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Martinsdale Colony vary in size. Copy the legal description from the record for the parcel near Springwater Colony when you talk to a surveyor.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Springwater Colony, so load it before you lose signal. A saved image of the lot near Judith Gap and its lines keeps working without signal.
