Explore Calumet, Pennsylvania, 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 Calumet, Pennsylvania. 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 Pennsylvania 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 Calumet.
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.

Calumet emerges from the landscape where the Welty Run carves a persistent, narrow path through the earth, marking the terrain with the quiet industry of moving water. It lies 6.9 miles south-southeast of Greensburg, PA (from Greensburg, PA: bearing 156°T), and is situated 9.4 miles southwest of Latrobe. The surrounding topography is defined by the steady, unyielding rise of the Allegheny Plateau, where the air often holds a silver clarity that sharpens the edges of the distant Allegheny Mountains against the horizon. To the west, the land deepens into the quiet geography of Simpson Hollow, while the proximity of Mammoth Lake and the adjacent grounds of Unknown Park offer a stillness that contrasts with the rhythmic, mechanical pulse of the region's industrial heritage. The light at dusk here possesses a particular quality, filtering through the canopy of the nearby Forbes State Forest to cast long, violet shadows across the fields that seem to hold the day’s heat in the soil long after the sun has retreated.
Calumet carries the weight of a history forged in the extraction of coal and the labor of those who settled the rugged terrain to feed the furnaces of the wider region. Where coal dust once settled on the windowsills, a transformed economy now persists, shifting away from the heavy extraction that defined the nineteenth and twentieth centuries toward a quieter, more dispersed way of life. The remnants of this past are visible in the structural bones of the streets and the faded brickwork of older buildings that anchor the local identity. Residents observe a pace that mirrors the slow, seasonal turn of the Pennsylvania landscape, finding continuity in the familiar sight of the Welty Run and the enduring presence of the hills that frame the horizon. Even as the decades alter the character of labor, Calumet remains a place where the connection to the earth—its minerals, its timber, and its water—remains the primary measure of existence.

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.
