How to Use This Dewey, Montana Map

This interactive map shows the street layout and satellite imagery for Dewey, 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 Dewey.

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.

About Dewey, Montana

Dewey is a locality in Beaverhead County, Montana, United States. It is a small community with a population of 25. The population density is 36.6 people per km². Dewey is located at 45.7771°N, 112.8550°W. It observes the Mountain Time (America/Denver) timezone. ZIP code: 59727.

Dewey sits low in the earth, defined by the persistent, cold-running pulse of the Big Hole River that carves its path through the landscape. It lies 22.0 miles southwest of Butte, MT (from Butte, MT: bearing 225°T), and is situated 24.6 miles south of Anaconda. Quartz Hill Gulch opens wide here, a rugged basin where the light at dusk flattens against the sagebrush, turning the high plains into a vast, muted canvas of copper and slate. While the distant, jagged line of the Rocky Mountains haunts the far western horizon, the immediate ground is defined by the intimate, uneven textures of the gulch floor. Four miles to the north, the waters of Cattle Gulch Lake settle into a quiet, reflective stillness, providing a rare anchor of depth in a terrain otherwise dominated by the expansive, dry reach of the Montana sky.

Dewey remains a place where the economy is tethered to the slow, deliberate work of the land and the seasonal rhythms of the riverbanks. The George Grant Memorial Fishing Access Site serves as a primary waypoint for those drawn to the water, marking a point of intersection between the local ranching legacy and the transient movement of visitors seeking the solitude of the river. The labor here is quiet, often involving the maintenance of fences or the management of acreage that has been held by families for generations, far removed from the denser timber stands found toward the Beaverhead National Forest. Life in Dewey follows the shifting colors of the grasses and the unpredictable temperament of the weather, maintaining a stubborn, solitary character that persists long after the daily work is done.

About This Dewey Map Page

This page provides an embedded street and satellite map of Dewey, Montana. Coordinates: 45.777148, -112.855033. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Dewey includes the ZIP code (59727), telephone area code (406), county seat of Beaverhead County (Dillon), and school district assignment (Beaverhead County High School District).

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.
