How to Use This Mill Run, Pennsylvania Map

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

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 Mill Run, Pennsylvania

Mill Run is a locality in Blair County, Pennsylvania, United States. It is a small community with a population of 231. The population density is 295.3 people per km². Mill Run is located at 40.5055°N, 78.4331°W. It observes the Eastern Time (America/New_York) timezone. ZIP codes: 15464, 15849, 19040.

Mill Run serves as a quiet witness to the enduring reach of the Allegheny Mountains, which rise in a jagged, slate-colored line three miles to the horizon. It lies 2.3 miles west-southwest of Altoona, PA (from Altoona, PA: bearing 251°T), and is situated 6.1 miles north-northwest of Hollidaysburg. The water of Mill Run carves a persistent path through the landscape, its current often muted by the heavy, damp soil and the dense stands of hardwood that define the plateau. Light here possesses a peculiar, filtered quality, thinning as it settles into the hollows before dusk, casting the earth in shades of bruised plum and charcoal. To the west, the topography softens slightly toward the reaches of Carson Valley, while the proximity of the Allegheny Reservoir ensures that the air remains perpetually thick with the scent of damp moss and cooling stone.

Westfall Park offers a singular expanse of managed green space just one mile from the center of Mill Run, providing a necessary breath of open ground against the encroaching thickets. The economy of the region has long been tethered to the slow, deliberate extraction and processing of the earth’s raw materials, a tradition that leaves the mark of iron and timber on the local character. Life in Mill Run moves with a gravity that honors the past, where the labor of previous generations persists in the sturdy, unadorned architecture of the dwellings. It is a place where the rhythm of the day is dictated not by the hurried pulse of the city, but by the steady, seasonal shifts of the woodland and the quiet persistence of the valley floor.

About This Mill Run Map Page

This page provides an embedded street and satellite map of Mill Run, Pennsylvania. Coordinates: 40.50553, -78.433132. 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 Mill Run includes the ZIP code (15464, 15849, 19040), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of Blair County (Hollidaysburg), and school district assignment (Altoona 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.
