Explore Williamstown, 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 Williamstown, 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 Williamstown.
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.

Williamstown occupies a rugged stretch of terrain where the landscape is defined by the steady, persistent flow of Wiconisco Creek. It lies 16.3 miles north-northeast of West Hanover, PA (from West Hanover, PA: bearing 24°T), and is situated 8.0 miles southwest of Hegins. The air here holds a crisp, earthen clarity, often carrying the scent of damp moss and shifting minerals from the surrounding ridges. To the north, the ground climbs toward the distant silhouettes of the Blue Ridge Mountains, while the local horizon remains anchored by the quiet presence of Veterans Memorial Park. Sunlight catches the shale-streaked slopes during the late afternoon, casting long, sharp shadows that emphasize the severe, honest lines of the earth. Beyond the immediate town limits, the terrain softens into the dense, shaded canopy of Haldeman State Forest, providing a sanctuary of quiet growth that contrasts with the open, wind-swept patches of the valley floor.
Williamstown grew from the deep, anthracite-rich veins of the earth, a history that remains visible in the sturdy, deliberate architecture of its older buildings. The economy once turned entirely upon the coal beneath the surface, leaving behind a legacy of endurance that persists in the way the residents maintain their properties and gather in common spaces. While the industrial fervor has receded, the rhythm of daily life remains tethered to the land, influenced by the proximity of the Greenland Trail, where the path winds through terrain once bustling with activity. On quiet days, the water levels of the Lebanon Reservoir, six miles distant, represent the primary stillness of the district, serving as a reminder of the water that shaped this basin. The character of Williamstown is marked by this transition from extraction to a steady, patient existence, where the weight of the past is not a burden but a foundation for the present.

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.
