Before an offer near Dubois, check the Lander flood zone map: FEMA's zone label affects insurance, permits and resale. What this Lander guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Checking the Lander flood zone map step by step
The official source is FEMA's Flood Map Service Center: type an address near Pavillion, then open the map view for that panel. Vacant ground around Riverton is still easy to locate: pan from the closest town and click the spot.
Pulling up a parcel
The no-cost parcel map for this area is the Fremont County Beacon site, and no login is needed to use it. In and around Shoshoni, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Dubois, the record panel typically gives the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Water near Hudson
Low-lying fields near Shoshoni may not have detailed mapping, so look for water marks and debris lines. Wet ground around Pavillion is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Lander, WY: the basics
Lander sits in Fremont County, Wyoming, so its parcels are on the county's map. Lander is also the county seat, handy when you need recorded documents. For a parcel near Pavillion, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits near Pavillion generally follows county rules instead.
How land is described here
Wyoming uses the Public Land Survey System, which means a tract near Dubois 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 real sections near Riverton vary in size. Write down the legal description for the tract near Pavillion when you talk to a surveyor.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; surveyors near Hudson use that number. If you're looking near Pavillion, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the Fremont County Beacon site to see exactly which lot near Hudson you're looking at.
What to request from a seller
Request for any Elevation Certificate for the house near Shoshoni; an insurance quote early avoids surprises.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Pavillion sit with the County Clerk. Long-held tracts near Shoshoni can sit on several deeds, and a title company earns its fee on a real sale.
When a parcel crosses a boundary
Fremont County meets Carbon County, Hot Springs County, Natrona County, Park County, and Sublette County, and each of those keeps its own parcel map. A tract near the line by Riverton can be split in two county records, so check the adjacent map as well. In and around Dubois, the Platbookmapper state page links each bordering county map across Wyoming.
Money questions tied to the zone
Around Pavillion, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Shoshoni in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
Places you'll see on the map
Lander is the county seat, home to the main records offices. Smaller places on the map include Hudson, Riverton, Dubois, and Pavillion, each with its own cluster of lots. About 39,815 people call Fremont County home (Census estimate, 2023) spread over some 9,184 square miles. Fremont County dates to 1884, which matters when you trace an old farm's title. Features like Yellowstone National Park make handy reference points on the map near Riverton.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor can set the real lines for a parcel near Riverton. If the land is near Shoshoni, owner names and values update on a schedule, so a deed recorded last month may not show yet.

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.
