Explore Dumb Hundred, 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 Dumb Hundred, 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 Dumb Hundred.
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.

Dumb Hundred occupies a basin of quiet, deliberate earth where the Halter Creek carves a persistent path through the limestone-heavy soil. It lies 13.9 miles south of Altoona, PA (from Altoona, PA: bearing 183°T), and is situated 7.7 miles south of Hollidaysburg. The landscape surrounding Dumb Hundred consists of deep-shadowed woodlands and stubborn, clay-packed fields that hold the morning frost long after the sun has climbed the sky. To the west, the silhouettes of the Allegheny Mountains break the horizon, their jagged crests suggesting a rugged barrier against the wider world. Closer to the soil, the terrain softens into the gentle, verdant expanse of Shawnee Park, where the vegetation clings to the damp ground with a tenacity born of long, grey winters. The light here at dusk possesses a singular, bruised quality, turning the canopy of the nearby woodlands into a series of dark, overlapping planes that seem to hum with the cooling air.
Industry in Dumb Hundred remains anchored to the slow, mechanical pulse of the interior, drawing its strength from the remnants of older labor and the cultivation of the surrounding valley floors. While the proximity of Wolf Hollow provides a natural drainage that once supported small-scale milling operations, the current economy relies on a quiet endurance, with residents maintaining a rhythm dictated by the seasons rather than the frantic pace of the larger hubs. History here is not written in grand monuments, but in the sturdy, unadorned architecture that lines the local thoroughfares, reflecting a heritage of modest craftsmanship. Residents often look toward the Hollidaysburg Reservoir when the summer heat hangs heavy, finding a brief respite in the stillness of the water. Life in Dumb Hundred persists as a series of small, necessary actions, defined by the steady flow of the creek and the enduring, stoic presence of the ridges that frame the view.

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.
