Explore Allison, 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 Allison, 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 Allison.
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.

Allison occupies a landscape defined by the persistent, rhythmic southward flow of Dunlap Creek as it carves through the undulating terrain of the Allegheny Plateau. It lies 12.5 miles south-southwest of Rostraver, PA (from Rostraver, PA: bearing 194°T), and is situated 10.0 miles northwest of Uniontown. The earth here carries a somber, heavy quality, shifting from the dense, dark loam of the fields to the exposed, weathered shale that marks the nearby descent into Shear Hollow. On clear afternoons, the distant, hazy silhouette of the Allegheny Mountains suggests a boundary beyond the immediate horizon, while the local air remains cool and damp, carrying the scent of rich, upturned soil and the faint, metallic sharpness of a region long shaped by its subterranean wealth. At the edge of the residential grid, the Allison Ballfield provides a flat, open clearing where the late-day light stretches long shadows across the grass, grounding the neighborhood in a quiet, communal stillness.
History in Allison remains anchored to the legacy of the coal industry, which once dictated the architecture and the very layout of the streets, leaving behind a collection of sturdy, utilitarian houses that mirror the grit of earlier generations. While the massive extraction operations have faded into memory, the local economy continues to pivot toward the modest rhythms of regional commerce and the slow transition of land back to forest and scrub. Life moves with an unpretentious pace, marked by the occasional sound of trucks navigating the narrow roads or the quiet activity centered around the local fields. Even as the wilder growth of Forbes State Forest slowly reclaims the margins of the surrounding hills, the people of Allison maintain a distinct identity, one formed by the intersection of industrial heritage and the enduring, quiet presence of the water and the woods.

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.
