The Natrona County plat book: start here
If you're looking near Medicine Bow National Forest, a plat book is a privately published atlas, showing rural owners and tract lines, page by page across the county.
The free map to start with
Your first stop is the Natrona County ArcGIS parcel map; it covers each tax parcel from Evansville to Pathfinder National Wildlife Refuge. On ground around Evansville, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Medicine Bow National Forest, the record panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
How land is described here
Wyoming uses the Public Land Survey System, which means a tract near Alcova 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 Brookhurst odd-sized. Copy the legal description from the record for the parcel near Casper for any title or survey request.
The paper trail behind a parcel
Before you sign anything, pull the recorded deed through the County Clerk; the viewer just points to it, for land near Medicine Bow National Forest included. In and around Bar Nunn, use the book and page shown in the record panel so staff can find the deed fast.
Offices that can help
Anything recorded against property around Edgerton come from the County Clerk, sometimes only in person. Zoning, permits and septic questions near Midwest are for the local planning and health departments, and the answer depends on jurisdiction.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Antelope Hills, though signal can drop in rural spots. A screenshot of the parcel near Casper Mountain with its ID helps when you meet an owner or agent.
Buying or borrowing a copy
Not every county has a current edition, check with local offices and farm stores near Pathfinder National Wildlife Refuge.
Before you lean on the lines
Parcel lines are drawn for taxes, not measured on the ground, so a fence near Casper often sits some distance off the line on screen. Out toward Bar Nunn, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Places you'll see on the map
Casper holds the county offices, home to the main records offices. You'll also find Bar Nunn, Edgerton, Evansville, and Midwest. Around 79,941 people call Natrona County home (Census estimate, 2023) on about 5,341 square miles. Places such as Medicine Bow National Forest are easy to spot when you zoom out.

Not the same thing
If the land is near Bessemer Bend, 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.
When a parcel crosses a boundary
The county touches Carbon County, Converse County, Fremont County, Johnson County, and Washakie County, and each of those keeps its own parcel map for land near Alcova. Acreage along the edge near Bessemer Bend may be split in two county records, so open the adjacent map too. For property near Edgerton, our state page lists every neighboring county map for Wyoming.

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.
