Looking for a Park County plat book? These atlases map who owns rural land, page by page, useful for farms near Corwin Springs. What this Park County guide covers: how the atlas is organized, where to look for printed copies, and how the county viewer fills the gaps.
The Park County plat book: start here
Near Gardiner, a plat book is a privately published atlas, with owner names on each tract, usually township by township.
The free map to start with
Go first to the Park County ArcGIS parcel map; it maps each assessed parcel from Corwin Springs to Emigrant. If the land is near Clyde Park, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Emigrant, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Which office to call
Deeds, mortgages and recorded plats for land near Livingston come from the County Clerk and Recorder, often with an online index. Building or septic questions for a lot near Emigrant go to planning, building or health offices, depending on whether the land is inside town limits.
Editions and availability
Editions come and go depending on publishers, try the county extension office, recorder's office or library near Gardiner.
How land is described here
Montana is laid out under the Public Land Survey System, so deeds around Jardine reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Custer National Forest odd-sized. Write down the legal description for the tract near Clyde Park for any title or survey request.
Next door to Park County
Park County touches Carbon County, Gallatin County, Meagher County, Stillwater County, and Sweet Grass County, all with their own assessor records. Ground near Corwin Springs that runs to the line may show up across two assessors' files, so check the neighboring map as well. For property near Yellowstone National Park, the Platbookmapper state page links every bordering county map across Montana.
Making your own township pages
Print parcel views near Gardiner township by township to build your own up-to-date atlas.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Emigrant, though signal can drop in rural spots. A printout of the tract near Clyde Park keeps working without signal.
The paper trail behind a parcel
The map is an index, not the title: deeds, plats and easements for land near Cooke City sit with the County Clerk and Recorder. If the land is near Jardine, bring the book and page shown in the record panel to skip a name search.
Using the parcel viewer instead
The Park County ArcGIS parcel map is updated more often than any atlas, for tracts near Gallatin National Forest.
Two kinds of plat
For a tract near Gallatin National Forest, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Clerk and Recorder is a legal document, while the atlas is a reference.
Why people still buy them
Buyers and seed dealers around Clyde Park rely on them for a big-picture view of who owns what.
Before you lean on the lines
For acreage around Jardine, listed acreage is an estimate; just a licensed surveyor establishes the real boundary on the ground. For a home near Cooke City, records update in batches, so a deed recorded last month might lag behind.
Getting your bearings
Livingston serves as the county seat, which is where the courthouse records live. Smaller places on the map include Clyde Park, Cooke City, Corwin Springs, and Emigrant. About 17,903 people call Park County home (Census estimate, 2023) across about 2,802 square miles. The county dates to 1887, and some chains of title near Custer National Forest are long. Landmarks such as Yellowstone National Park help you orient on the aerial.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
