Where to find the official Madison County GIS map
The Madison County ArcGIS parcel map is the county's own public parcel viewer; it runs on an Esri ArcGIS web map. A one-time disclaimer stands between you and the Madison County parcels; accept it to continue. The quickest search in Madison County is usually the parcel number from a tax bill; owner and address searches work too. We keep the link current on our Madison County (MT) directory page, next to the neighboring maps.
How accurate are Madison County, MT property lines?
On rural tracts near Brandon, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. Because Montana is a section-township-range state, the legal description of a rural tract in Madison County reads like a grid reference that you can match to the section lines on the map. For walking the corners yourself, our guide to finding property corners helps; for a legal answer, call a Montana licensed surveyor.
What the map covers, from Virginia City to the back roads
On the map, Virginia City anchors the county as its seat, with Ennis, Sheridan, and Twin Bridges spread around it. You'll also find unincorporated communities, among them Alder, Big Sky, and Brandon. The Census Bureau puts Madison County at about 3,588 square miles of land and an estimated 9,521 people (2023). With so few people per square mile, the county's parcel layer is dominated by big rural tracts, and a single click outside Ennis can land on a quarter section or more. On the parcel layer, Beaverhead National Forest and Deerlodge National Forest show up as public ground, and the private tracts along their edges are worth checking line by line.
Hunters: whose land is it?
Near Ennis, a single field edge can separate two owners with very different answers about access; the map tells you which is which. Around Beaverhead National Forest and Deerlodge National Forest, private tracts can press right up against the public boundary, so check the lines before you walk in. For licenses, seasons and public hunting land, go to the Montana Fish, Wildlife and Parks. In the field near Twin Bridges, respect posted signs and painted boundaries even where the map line looks different.
Behind the map: land records in Madison County
For land near Twin Bridges, the parcel record is the index; the recorded deed is the source. Check the county government website to see which office records deeds for land near Brandon. When the chain of title matters for land near Virginia City, ask for the full deed history or hire a title company in Montana.
Who needs this map
The same map serves very different jobs around Ennis. Hunters near Virginia City check the lines before opening day so a blood trail or a retrieve doesn't cross onto a neighbor's ground uninvited. Homesteaders eyeing the country near Brandon use acreage and frontage on the record to narrow a long list to a few tracts worth visiting. An owner in Virginia City planning a fence or an outbuilding pulls the parcel first, then the recorded plat.
Data limits to keep in mind
A lot in Ennis that sold last month may still show the previous owner on the map. Treat Madison County acreage figures as estimates until a survey confirms them.
