Explore Port Allegany, 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 Port Allegany, 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 Port Allegany.
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.

Port Allegany occupies a quiet expanse of the Pennsylvania landscape where the earth rises in slow, deliberate folds toward the horizon. It lies 30.2 miles north-northeast of Saint Marys, PA (from Saint Marys, PA: bearing 29°T), and is situated 20.0 miles south-southeast of Olean. Lillibridge Creek carves a persistent path through the terrain, its waters reflecting the muted greens and browns of the surrounding canopy as it flows past the local topography. Beyond the immediate reach of the town, the dense timber of the Susquehanna State Forest blankets the higher ground, while the nearby depression of Steel Hollow adds a distinct depth to the local geography. The air here holds a crisp, earthen clarity, particularly during the transition of seasons when the light thins to a pale, translucent gold that catches the edges of the valley walls. Residents find a familiar stillness in the proximity of the wilderness, where the distant, hazy silhouette of the Allegheny Mountains serves as a constant, immovable backdrop to the daily routine.
Port Allegany preserves a legacy rooted in the industrious spirit of the region’s early development, where the extraction of timber and the manufacture of glass once defined the rhythm of labor. While the echoes of those heavy industries have softened, the community maintains a steady pace, anchored by the Oak Street Swimming Pool which serves as a seasonal gathering point for the neighborhood. Life moves with an unforced cadence, whether one is seeking the quiet solitude of the Brown Hollow Number 3 Trail or reflecting by the calm, secluded surface of Simpson Cove. This locality is defined by a sense of permanence, where the architecture of the streets mirrors the resilience of those who have long called this particular stretch of Pennsylvania home. It is a place where the passage of time is measured not by grand events, but by the subtle, persistent changes in the woodland shadows and the dependable flow of the local creek.

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.
