Explore Hadley, 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 Hadley, 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 Hadley.
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.

Hadley occupies a quiet intersection of the Pennsylvania landscape where the Little Shenango River winds its path through the verdant, low-lying fields. It lies 16.3 miles south-southwest of Meadville, PA (from Meadville, PA: bearing 195°T), and is situated 8.9 miles east-northeast of Shenango. The light here at dusk possesses a singular, bruised quality, casting long shadows across the pastures that stretch toward the horizon. Three miles distant, the waters of Lake Wilhelm hold the reflection of the sky with a mirror-like stillness, anchoring the surrounding woods in a heavy, humid peace. Even from this distance, the terrain feels defined by the persistent, slow-moving current of the river, which carves a modest corridor through the earth, separating the stands of timber from the open, working ground.
Hadley maintains a rhythm dictated by the land, far removed from the clamor of the Appalachian Mountains that loom as a faint, hazy suggestion of height far to the east. The local economy remains tethered to the patterns of the harvest and the small-scale commerce that keeps the neighborhood functioning through the changing seasons. Residents often find their way to Commodore Perry Community Park for a brief respite, a space that serves as a common ground for the slow passage of days. While the echoes of deeper history reside in the memory of the region, the present life of Hadley is marked by the steady, unadorned diligence of those who navigate the distance between the riverbanks and the nearby expanse of McMillen Hollow.

Detailed location data for Hadley includes the ZIP code (16130), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of Mercer County (Mercer), and school district assignment.
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.
