How to Use This Grassflat, Pennsylvania Map

This interactive map shows the street layout and satellite imagery for Grassflat, 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 Grassflat.

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.

About Grassflat, Pennsylvania

Grassflat is a locality in Clearfield County, Pennsylvania, United States. It is a small community with a population of 479. The population density is 163.5 people per km². Grassflat is located at 41.0026°N, 78.1145°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 16839.

Grassflat occupies a rugged stretch of the Allegheny Plateau where the earth remains defined by the deep, persistent shadows of dense woodland and the quiet persistence of the wind. It lies 19.6 miles northwest of State College, PA (from State College, PA: bearing 317°T), and is situated 9.2 miles northeast of Philipsburg. Grassflat sits amidst an expanse of broken terrain where the thin, clear waters of Grassflat Run trace a cold path through the surrounding brush. Beyond the immediate clearings, the land swells into the distant, hazy silhouettes of the Allegheny Mountains, while the air carries the sharp, clean scent of pine needles and damp earth. A few miles away, the dark, still surface of Black Moshannon Lake mirrors the canopy of the Moshannon State Forest, and the quiet reaches of Sawdust Hollow provide a low basin for the evening mist to gather. During the autumn months, the light turns a brittle, pale gold, illuminating the steep slopes and casting long, skeletal shadows across the narrow roads that wind toward Arc Park.

Industry once pulled its vitality from the deep seams of the ground, leaving Grassflat with a character forged in the grit of coal mining and the slow, steady reclamation of the forest. The economy here shifted as the extraction slowed, transitioning into a way of life that values the stillness of the high plateau and the rugged accessibility of the Old Huckleberry Trail. Residents move with a deliberate, measured pace, finding a certain resilience in the isolation that comes from living so far from the reach of the coast. The legacy of the men who labored in the mines remains present in the sturdy architecture and the quiet, unadorned pride of the streets. Here, the passage of time is measured not by the clock, but by the turning of the leaves and the way the frost settles over the fields before the first heavy snows arrive to insulate the land.

About This Grassflat Map Page

This page provides an embedded street and satellite map of Grassflat, Pennsylvania. Coordinates: 41.002557, -78.114454. 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 Grassflat includes the ZIP code (16839), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of Clearfield County (Clearfield), and school district assignment (West Branch Area 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.
