Explore Forty Mile Colony, 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 Forty Mile Colony, 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 Forty Mile Colony.
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.

Forty Mile Colony occupies a quiet stretch of high prairie where the horizon seems to pull the sky down until it touches the earth in a thin, shimmering line. It lies 66.0 miles east-southeast of Billings, MT (from Billings, MT: bearing 122°T), and is situated 34.4 miles south-southeast of Hardin. The land here is defined by a rigorous, horizontal patience, broken only by the deliberate incision of Owl Creek, which marks the low ground a mile away with a thin ribbon of willow and silt. Beyond the immediate flatlands, the terrain tilts toward the distant, jagged silhouette of the Rocky Mountains, though they remain a faint, ethereal promise far to the west. On clear afternoons, the light turns a hard, pale gold, stripping the shadows from the dry stalks of grass and revealing the austere geometry of the soil. Six miles out, the earth drops away into the rugged, shadowed depths of Cook Stove Canyon, a place where the wind gathers speed and carries the scent of sagebrush and cooling dust across the plains.
History in Forty Mile Colony is measured in the persistence of those who worked the soil long before the modern silos claimed their place against the clouds. The economy remains tethered to the slow, demanding cycles of agriculture, a life of early mornings spent tending to the needs of livestock and the seasonal harvest that dictates the rhythm of the year. While the Montana State Trust Lands lie sixteen miles away as a reminder of the vast, protected wild, the daily concerns here are centered on the fence line and the condition of the road leading toward the water of Liming Reservoir. There is a particular, quiet dignity in the way the local life unfolds, stripped of pretense and focused on the practicalities of a harsh climate. People move with the steady, unhurried gait of those who have spent years navigating the immense scale of the plains, finding purpose in the maintenance of their own small, hard-won corner of the world.

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.
