Explore Northumberland, 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 Northumberland, 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 Northumberland.
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.

Northumberland occupies a convergence of low-lying terrain where the land yields to the persistent, rhythmic flow of the West Branch Susquehanna River. It lies 19.5 miles west-southwest of Bloomsburg, PA (from Bloomsburg, PA: bearing 247°T), and is situated 2.8 miles north-northwest of Hamilton. {NAVIGATION} The earth here is heavy with alluvial silt and the quiet gravity of the interior, situated far from the reach of any oceanic influence. Beyond the immediate banks, the horizon is defined by the distant, jagged silhouette of the Appalachian Mountains, which anchor the sky in a permanent, hazy blue. Within the boundaries of Northumberland, the local landscape finds a center of gravity at Northumberland Borough Park, where the grass grows thick and the air holds the damp, metallic scent of moving water. Light at dusk here does not dissipate but pools in the low spots, turning the gray stone of the streets into a soft, polished slate.
History clings to the brick foundations of Northumberland, marking it as a place where the early commerce of the frontier once turned upon the movement of cargo and the labor of the river trades. The economy has shifted from those original mercantile rhythms, yet the pace remains tethered to the slow turn of the seasons and the cycle of the inland harvest. Those seeking the solitude of the woods often travel toward the quiet stillness of Sunshine Fines Pond or trace the long, winding dirt of James Path, while others find their way toward the deeper recesses of Jews Hollow. Life in Northumberland persists with a steady, unadorned composure, defined by the sound of the river against the stones and the endurance of a landscape that has seen the transformation of the valley from timber and coal to the quiet, persistent work of the present day.

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.
