How to Use This Boulder, Montana Map

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

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 Boulder, Montana

Boulder exists as a quiet anchor in a landscape defined by the persistent, cold-clear rush of the Boulder River, which carves a path through the valley floor. It lies 24.9 miles south of Helena, MT (from Helena, MT: bearing 189°T), and is situated 25.5 miles northeast of Butte. The horizon is dominated by the vast, open sky that presses down upon the high plains, while the distant silhouettes of the Big Belt Mountains offer a jagged, violet boundary to the east. Nearby, the terrain folds into the narrow drainage of Poore Gulch, and the surface of Taylor Reservoir catches the silver light of dawn, reflecting the sparse, wind-bent pines that populate the surrounding hills. The air here carries a sharp, metallic clarity, often smelling of damp earth and sagebrush, particularly in the hours when the sun retreats behind the western ridges and the shadows lengthen across the valley.

Boulder maintains a rhythm dictated by the seasonal shifts of the land and the endurance of those who work the timber and the ranching spreads that stretch toward the Montana State Trust Lands. Originally established as a hub for miners and travelers navigating the rugged interior, the economy now rests upon a blend of small-scale commerce and the stewardship of the surrounding wild expanses. The architecture remains functional and unadorned, favoring sturdy timber and weathered siding that withstand the long, hard winters. Life in Boulder proceeds without pretense, characterized by a persistent stillness that allows the sound of the wind through the tall grasses to become the primary language of the day.

About This Boulder Map Page

This page provides an embedded street and satellite map of Boulder, Montana. Coordinates: 46.236595, -112.120834. 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 Boulder includes the ZIP code (59632), telephone area code (406), county seat of Jefferson County (Boulder), and school district assignment (Boulder Elementary 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.
