Explore Tunnelhill, 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 Tunnelhill, 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 Tunnelhill.
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.

Tunnelhill occupies a rugged expanse of the high plateau, defined by the persistent, rhythmic cutting of Sugar Run as it carves through the terrain. It lies 8.2 miles west-southwest of Altoona, PA (from Altoona, PA: bearing 250°T), and is situated 8.7 miles west-northwest of Hollidaysburg. The landscape is dominated by the looming presence of the Allegheny Mountains, which rise to the east like a somber, slumbering giant, casting long shadows that swallow the light well before the sun reaches the horizon. Dense woodlands press against the edges of the streets, and the sprawling acreage of State Game Land 198 provides an unbroken mantle of green that stretches into the distance, indifferent to the small human dwellings scattered in its wake. When the autumn air turns crisp, the light here takes on a pale, translucent quality, illuminating the deep ravines where the earth seems to hold its breath in the quiet solitude of the highlands.
Tunnelhill retains the echo of a period defined by the iron and steam that once propelled the region’s industry, though the current pace of life is measured by the slow turn of the seasons rather than the clatter of heavy machinery. The economy has shifted away from the frantic extraction of earlier years, leaving the inhabitants to find their rhythm in the stillness of the surrounding woods and the proximity of the wilder reaches of the landscape. While the waters of the Allegheny Reservoir lie only a few miles distant, they remain a distant mirror to the life of the village, which turns its gaze toward the sheltered slopes of Christie Hollow and the quiet persistence of its own local tracks. There is a singular, quiet dignity in how Tunnelhill persists, a place where the weight of history is felt not in monuments, but in the enduring character of those who live under the shadow of the ridges.

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.
