The Riverton plat map: start here
For land around Shoshoni, the deed usually cites the plat; that makes the request quick.
Getting to the right map
Begin with the Fremont County Beacon site; it maps each tax parcel around Lander and Shoshoni. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, which applies near Pavillion as much as anywhere. In and around Pavillion, write down the parcel ID from that panel; every office in the county asks for it first.
Land on the county line
Fremont County meets Carbon County, Hot Springs County, Natrona County, Park County, and Sublette County, all with their own assessor records. A tract near the line by Shoshoni can show up across two assessors' files, so look at the adjacent map too. Our state page lists every neighboring county map for Wyoming.
Getting answers from the right desk
For assessment questions about property around Hudson go to the County Assessor, the office behind the parcel record. Questions about what you can build around Pavillion go to planning, building or health offices, town or county, depending on location.
What the map can't tell you
Listed acreage is an estimate; just a licensed surveyor establishes the real boundary for a parcel near Pavillion. Closer to Pavillion, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Riverton, WY: the basics
Riverton lies within Fremont County, Wyoming, so its parcels are on the county's map. Around Dubois, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits toward Dubois often falls under county rules instead.
A quick look at the area
Lander holds the county offices, where most land records are kept. You'll also find Hudson, Dubois, and Pavillion, where town lots give way to larger tracts. About 39,815 people call Fremont County home (Census estimate, 2023) on some 9,184 square miles. Fremont County dates to 1884, so old deeds can run back a long way. Features like Yellowstone National Park help you orient on the aerial around Lander.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Pavillion, but coverage can be spotty out of town. A saved image of the lot near Lander and its lines keeps working without signal.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements for land near Lander sit with the County Clerk. For a tract near Pavillion, have ready the document number listed on the parcel record so staff can find the deed fast.
When a plat changes
Lots near Shoshoni can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Metes and bounds instead
Rural land near Lander that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
How a plat differs from the tax map
The Fremont County Beacon site draws parcels for taxes, but the recorded plat is what the deed relies on.
What a plat shows
Utility or drainage strips on a lot in Riverton stay with the land when it sells; read the notes on the sheet.
Requesting the plat
For acreage around Shoshoni, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
How land is described here
Wyoming uses the Public Land Survey System, so deeds around Lander 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 Shoshoni vary in size. Keep the legal description for land near Dubois before you request a deed or survey.
