The Carbon County plat book: start here
With a lot near Boyd, plat books are commercial atlases, that map ownership across the countryside, usually township by township.
Getting to the right map
Your first stop is the Montana Cadastral; it covers each assessed parcel around Bearcreek and Big Horn River. When a rural tract has no street number, pan along the nearest road and select the outline, which applies near Bearcreek as much as anywhere. For a tract near Bridger, the record panel usually lists the owner of record, assessed acreage, the parcel number and often a sale date.
What the map can't tell you
Around Boyd, the acreage figure is a tax-roll number; just a licensed surveyor sets the real lines on the ground. Out toward Joliet, owner names and values update on a schedule, so a deed recorded last month may not show yet.
The paper trail behind a parcel
When the details count, request the recorded deed through the County Clerk and Recorder; the parcel line is a drawing of it, for land near Boyd included. Long-held tracts near Big Horn River may go back through a long string of deeds, and a title company earns its fee before a purchase.
Places you'll see on the map
Red Lodge is the county seat, home to the main records offices. Smaller places on the map include Bearcreek, Bridger, Fromberg, and Joliet. About 11,419 people live in Carbon County (Census estimate, 2023) spread over about 2,048 square miles. Carbon County was organized in 1895, and some chains of title near Bighorn Canyon National Recreation Area are long. Landmarks such as Big Horn River and Bighorn Canyon National Recreation Area are easy to spot when you zoom out.

Ground near Boyd that runs to the line can show up across two assessors' files, so look at the neighboring map before you assume the acreage. For acreage around Big Horn River, the Platbookmapper state page lists every neighboring county map for Montana.
Finding a printed edition
Editions come and go depending on publishers, check with local offices and farm stores near Custer National Forest.
Current ownership online
Between printed editions, the Montana Cadastral shows current owners, including rural land around Fox.
Sections, lots and bearings
Montana is laid out under the Public Land Survey System, so rural legal descriptions near Red Lodge cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Custer National Forest vary in size. Copy the legal description from the record for the parcel near Joliet before you request a deed or survey.
Field tips
Most viewers work in a phone browser, useful out on a road near Edgar, but coverage can be spotty out of town. A printout of the tract near Edgar is a good backup.
Getting answers from the right desk
Deeds, mortgages and recorded plats for land near Bearcreek are with the County Clerk and Recorder, sometimes only in person. Building or septic questions for a lot near Big Horn River are for the local planning and health departments, depending on whether the land is inside town limits.
Common uses
Buyers and seed dealers around Red Lodge rely on them for a big-picture view of who owns what.
Not the same thing
For property near Boyd, a plat book is not a recorded plat: the recorded plat at the County Clerk and Recorder is a legal document, while the atlas is a reference.
