Explore Pompeys Pillar, 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 Pompeys Pillar, 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 Pompeys Pillar.
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.

Pompeys Pillar commands the horizon as a massive, solitary sandstone monolith rising abruptly from the surrounding prairie floor. It lies 30.0 miles east-northeast of Billings, MT (from Billings, MT: bearing 61°T), and is situated 25.2 miles east-northeast of Lockwood. Fly Creek meanders through the landscape nearby, its waters carving a subtle path toward the life-sustaining current of the Yellowstone River, which flows just a mile from the base of the rock. To the west, the distant peaks of the Rocky Mountains trace a jagged, hazy silhouette against the high-plains sky, while the nearby Smith Coulee adds a rhythmic fracture to the otherwise expansive, wind-swept terrain. The light here is thin and clear, catching the golden grasses of the plains and casting long, indigo shadows that stretch across the earth as the sun dips toward the edge of the world.
History remains etched into the very face of Pompeys Pillar, where the weathered signature of William Clark serves as a singular, permanent mark left by the 1806 expedition. This landmark stands as a silent witness to the generations of travelers who have moved across the plains, trading the solitude of the open country for the necessity of the regional ranching economy. Life in the shadow of the pillar moves in accordance with the seasons, guided by the demands of the soil and the quiet endurance of those who work the land. While the modern world maintains its pace, the area retains an atmosphere of stillness, defined by the immense, pale sky and the persistent, low hum of the wind traversing the plains between the distant ranges and the riverbanks.

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.
