Explore Roundup, Montana, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Roundup, Montana. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of Montana or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Roundup.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Roundup asserts itself across the expansive, sun-bleached plains of Montana, where the horizon stretches thin and taut like a wire pulled against the sky. It lies 45.8 miles north of Billings, MT (from Billings, MT: bearing 358°T), and is situated 54.7 miles north-northeast of Laurel. The Musselshell River carves a deliberate path through the landscape, its waters often sluggish and silt-heavy, providing a singular, verdant ribbon that cuts through the dry, rugged terrain. To the north, Fletchers Coulee deepens the earth, creating shadows that lengthen with a melancholic grace as the afternoon sun begins its descent. The air here holds a crisp, arid quality, carrying the scent of parched sagebrush and the faint, metallic tang of distant, iron-rich soil. Beyond the immediate reach of the town, the land rises into subtle, golden swells that eventually lead the eye toward the distant, hazy silhouette of the Rocky Mountains, which loom like ghosts on the far western edge of the world.
Roundup emerged from the dust of the early twentieth century, built upon the hard-won wealth of coal and the persistent labor of those who saw opportunity in the seams beneath the prairie. The economy remains tethered to the rhythm of the land, shifting between the cycles of ranching and the remnants of an industrial heritage that once defined the region’s growth. Residents often look toward the Montana State Trust Lands for access to the open range, finding a quiet solitude in the vast, unpopulated stretches that define the perimeter of their daily lives. While Lake Mason provides a modest basin of stillness eight miles away, the character of the locality is defined more by the persistent wind and the resilience of the people who persist against it. Life in Roundup moves with a deliberate, steady cadence, unburdened by the frantic pace of larger centers, echoing the stoic endurance of the high plains themselves.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
