How to Use This Saint Clair, Pennsylvania Map
This interactive map shows the street layout and satellite imagery for Saint Clair, 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 Saint Clair.
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 Saint Clair, Pennsylvania
Saint Clair is a locality in Westmoreland County, Pennsylvania, United States. Saint Clair is located at 40.2687°N, 79.5484°W. It observes the Eastern Time (America/New_York) timezone. ZIP codes: 15042, 15210, 15601.Saint Clair occupies a rugged stretch of terrain where the landscape is defined by the persistent flow of Slate Creek cutting through the earth. It lies 2.3 miles south-southwest of Greensburg, PA (from Greensburg, PA: bearing 192°T), and is situated 5.4 miles southeast of Jeannette. The ground here holds a certain heaviness, a density of soil and stone that reminds those who walk it of the deep, subterranean layers beneath the surface. To the west, the distant peaks of the Allegheny Mountains catch the low, slanted light of late afternoon, turning a hazy, bruised purple against the sky. A mile away, the quiet surface of McMurrays Lake reflects the changing clouds, while the nearby South Greensburg Municipal Park offers a small, deliberate pause of green space amidst the steady, utilitarian rhythm of the streets.
Saint Clair grew from the marrow of the earth, its identity forged in the era when the ground beneath yielded its bounty to those willing to dig. The legacy of extraction lingers in the architecture of the older houses and the stoic, practical layout of the streets, which follow the uneven contours of the land rather than any clean grid. While the industrial pulse has shifted, the local economy retains a quiet, resilient character, moving with the measured pace of a place that has learned to endure long winters and quiet summers. Life here is measured in the familiar sounds of neighbors moving through their days, the scent of woodsmoke when the air turns sharp, and the way the shadows stretch long and thin across the porches as the day retreats into the hollows.

About This Saint Clair Map Page
This page provides an embedded street and satellite map of Saint Clair, Pennsylvania. Coordinates: 40.268681, -79.548373. 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 Saint Clair includes the ZIP code (15042, 15210, 15601), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of Westmoreland County (Greensburg), and school district assignment.
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.
