Explore Plum, 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 Plum, 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 Plum.
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.

Plum defines its borders through a series of slopes and depressions that characterize the rugged landscape of the western Pennsylvania plateau. It lies 3.7 miles south of Lower Burrell, PA (from Lower Burrell, PA: bearing 174°T), and is situated 4.7 miles east of Penn Hills. Little Plum Creek winds through the terrain, carving a path that provides a constant, rhythmic presence for those living near its banks. To the east, the distant silhouette of the Allegheny Mountains suggests a vast, elevated wilderness that stands in contrast to the local topography. Whitten Hollow offers a quieter, deeper recess in the land where the air feels heavier and cooler during the humid summer months. The quality of light here at dusk often turns the sky a bruised purple, casting long shadows across the uneven ground that defines the character of Plum.
Plum began its transformation from a sprawling rural expanse into a residential center, shedding its early agricultural skin to accommodate the movement of the regional workforce. Much of the local economy reflects the broader industrial heritage of the nearby steel corridors, though the focus has shifted toward modern service and administrative roles. Residents often look toward Beaver Run Reservoir as a reminder of the vital natural resources that sustain the broader region beyond the immediate neighborhood boundaries. The transition from mining and farming to suburban development has left behind a landscape that feels both industrious and quiet. Maintaining this balance requires a steady attention to the legacy of the land and the evolving needs of the families who build their lives in Plum.
Community life centers heavily on the Plum Borough Athletic Fields, where the energy of organized sports echoes across the grass throughout the changing seasons. These fields serve as a social anchor, drawing generations together for weekend matches that define the local calendar. Cultural identity in the region remains tied to a hardworking, unassuming spirit that values neighborliness over pretense. While the area is not defined by singular, world-famous monuments, it maintains a pride in its local institutions and the steady, unadorned pace of daily life. The residents here carry a quiet confidence, grounded by the reality of the earth beneath them and the enduring patterns of their own small-scale history.

This page provides an embedded street and satellite map of Plum, Pennsylvania. Coordinates: 40.500346, -79.749491. 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 Plum includes the ZIP code (15239, 15139), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of Allegheny County (Pittsburgh), and school district assignment (Plum Borough 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.
