Madison County spans a large part of southwestern Montana where Sheridan, Twin Bridges, Virginia City, and Ennis occupy different valleys separated by high mountain blocks. The northwest is organized around the Big Hole, Beaverhead, and Jefferson rivers, while the central and eastern county is shaped by the Ruby and Madison river valleys. Route 55 and Route 41 help locate Twin Bridges and Sheridan, while U.S. 287, Route 84, and Route 87 provide the strongest road references around Ennis and the eastern side. High-resolution JPG versions of the maps are available together in the download ZIP below.
Madison County’s official About page identifies Virginia City as the county seat and lists Ennis, Sheridan, Twin Bridges, and Virginia City as incorporated towns. That makes the supplied city map especially useful: Sheridan serves as the hub, but the four towns are spread across distinct valleys rather than one continuous urban corridor. The terrain-and-water and elevation maps explain those separations by showing large river valleys surrounded by mountain ranges.

Twin Bridges and Sheridan organize the northwestern road corridor
On the general county map, Twin Bridges lies in the northwestern interior, with Sheridan farther southeast. Route 55 descends from the Silver Star side toward Twin Bridges, and Route 41 continues south toward the southwestern boundary. Sheridan sits between Twin Bridges and Alder in a lower valley that provides one of the clearest settlement corridors on the western side.
Alder lies southeast of Sheridan, while Virginia City appears farther east beyond another mountain section. Mammoth and Pony are labeled farther north near higher terrain. In these mountain areas, roads are more widely spaced and the terrain-and-water map becomes increasingly useful for understanding the route between communities.
Butte-Silver Bow and Rader Creek appear outside the western boundary as regional reference points. These labels help with orientation but should not be treated as places inside Madison County. The road map is static, so current construction, winter closures, and remote-road conditions should be checked separately.

Ennis anchors the eastern Madison River valley
Ennis is the strongest settlement reference on the eastern side. U.S. 287 approaches from the north, Route 84 heads toward the eastern boundary, and Route 87 continues south through the long valley toward the county’s southern tip. McAllister lies directly north of Ennis and provides another useful marker along the same general corridor.
A road connection crosses the mountain interior from the Virginia City side toward Ennis. Big Sky appears as a separate area along the eastern boundary, while Ruby Valley Field is labeled farther north. The map makes clear that seemingly short map distances can involve mountain terrain and indirect road travel.
The alignment of U.S. 287 and Route 87 roughly follows the same broad north-south valley occupied by Madison River. Comparing the road and water maps helps explain why Ennis and McAllister sit where they do.
Sheridan is the hub for three straight-line city connections
The city-connections map uses Sheridan as the hub and links it with Twin Bridges, Virginia City, and Ennis. Its printed index lists Sheridan at 869, Ennis at 777, Twin Bridges at 201, and Virginia City at 129. These are values embedded in the supplied map and should not be treated as guaranteed current population estimates. Current demographic totals should be checked through recent U.S. Census Bureau data.
Twin Bridges is labeled 9 miles from Sheridan, Virginia City 17 miles, and Ennis 24 miles. All three measurements are straight-line distances rather than driving mileage. Actual road trips can be longer because the routes must follow valleys and cross or avoid mountain terrain.
The map also shows that the four towns do not form one straight settlement line. Twin Bridges lies northwest of Sheridan, Virginia City lies east, and Ennis sits farther east in another valley. The city view is therefore best used as a simple distance and location comparison, not as a road-routing map.

Big Hole, Beaverhead, and Jefferson rivers meet in the northwest
The terrain-and-water map makes the northwestern river junction one of the county’s most distinctive features. Big Hole River enters from the west, while Beaverhead River approaches from the south. Near the Twin Bridges side, the two river systems continue into Jefferson River, which leaves the county toward the north.
Numerous smaller tributaries descend into the Big Hole and Beaverhead valleys from surrounding mountains. The broad lower corridors explain why Twin Bridges is such a useful reference on both the road and water maps. The river junction is much easier to understand on the terrain view than on the road map alone.
The terrain-and-water map is intended for geographic reference. It does not establish flood zones, water depth, parcel boundaries, water rights, navigation conditions, or safe stream crossings. Current water and access conditions should be checked through the appropriate official sources.

Ruby River and Madison River occupy two long interior valleys
Ruby River runs north through the central-western county, with Ruby River Reservoir forming a major water body farther south. Spring Creek follows a separate valley to the west. Together these features help organize the Sheridan-Alder side beyond the main road labels.
Madison River dominates the eastern half, following a long north-south valley through the Ennis side. Near the southern boundary, West Fork Madison River forms a separate tributary. Quake Lake, Cliff Lake, and Hidden Lake provide additional landmarks in the southeastern and southern mountain country.
Hollowtop Lake sits in high terrain farther north, South Meadow Lake appears in the central-east, and Cedar Lake lies toward the eastern mountain side. These scattered lakes show how many separate high basins exist between the county’s two main river valleys.
Elevation ranges from about 1,282 to 3,408 meters
The elevation map reports an actual Madison County range of about 1,282 to 3,408 meters, with a mean elevation near 2,029 meters. The Big Hole, Beaverhead, Jefferson, and Madison river valleys appear in green as broad lower corridors, while large mountain blocks rise between them.
A major concentration of high terrain occupies the north-central interior around the Hollowtop Lake region. The eastern and southeastern county also contains extensive brown and dark-brown ridges, with Madison River cutting a lower green route between mountain ranges. Western valleys are generally more open even though high terrain rises around them.
The southern county contains repeated high ridges between the Ruby and Madison river systems. West Fork Madison River follows another lower corridor close to the boundary. The elevation map is intended for county-wide comparison only and should not be used as survey-grade or engineering-grade data for a specific property.

Sheridan, Ennis, and the major river valleys provide a simple framework
A practical way to read Madison County is to use Sheridan as the western settlement reference and Ennis as the eastern one. Around Sheridan, Twin Bridges, Alder, and Virginia City form the next set of landmarks. Around Ennis, McAllister and the U.S. 287-Route 84-Route 87 corridor explain the main road pattern.
Water features add another layer. Begin with the Big Hole-Beaverhead-Jefferson junction in the northwest, then follow Ruby River through the center-west and Madison River down the eastern side. Ruby River Reservoir, Quake Lake, Hollowtop Lake, and the smaller mountain lakes make the more remote areas easier to distinguish.
The WebP images embedded in the article are convenient for quick browsing. The high-resolution JPG files in the ZIP are better for printing or enlarging small road, river, and lake labels. Because these are static reference maps, current road access, water levels, and seasonal restrictions should be checked through current official information.
Frequently Asked Questions
Are the Sheridan-to-Twin Bridges, Virginia City, and Ennis distances driving distances?
No. The city map shows Twin Bridges at 9 miles, Virginia City at 17 miles, and Ennis at 24 miles from Sheridan as straight-line distances. Actual driving distances can be longer because roads follow mountain valleys rather than direct connector lines.
Where is the highest terrain in Madison County?
The highest terrain is concentrated in several central, eastern, and southeastern mountain blocks. The major river valleys around Twin Bridges, Sheridan, and Ennis are much lower.
Can the 1,282–3,408 meter elevation range be used for a property or engineering project?
No. The range is a county-wide reference for comparing low river valleys with high mountain terrain. Precise site elevations should come from an authoritative source such as the USGS 3D Elevation Program and, when necessary, a professional survey.
