How to Use This Potomac, Maryland Map

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

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 Potomac, Maryland

Potomac is a locality in Allegany County, Maryland, United States. It has a population of 47,018. The population density is 722.5 people per km². Potomac is located at 39.0133°N, 77.1936°W. It observes the Eastern Time (America/New_York) timezone. ZIP codes: 20854, 21502, 20817.

Potomac reveals itself through the steady, muscular current of the North Branch Potomac River, which carves a path through the dense, verdant terrain. It lies 6.3 miles south-southwest of LaVale, MD (from LaVale, MD: bearing 194°T), and is situated 7.2 miles southwest of Cumberland. The landscape here is defined by the heavy, humid weight of summer air and the quietude of deep woodlands that stretch toward the distant, hazy silhouette of the Appalachian Mountains. A mile away, the quiet surface of the Pinto Utilities Reservoir catches the late afternoon light, mirroring the somber gray of the sky as it moves toward dusk. Further out, the land dips into the shadowed basin of Koulip Hollow, where the earth feels older and the damp scent of moss lingers long after the sun has retreated.

Potomac remains a place where the remnants of agrarian legacies linger beneath the modern veneer of sprawling estates and private lanes. The local economy, once tied to the rugged yield of the soil, now moves with the soft, deliberate pace of those who sustain themselves through professional pursuits and the quiet maintenance of their properties. Nearby, the Bel Air Area Park provides a sanctuary of unmanicured grass and thicket, offering a glimpse of the wilderness that once claimed the entire region. Life in Potomac is marked by the slow turning of seasons against the persistent, ancient backdrop of the riverbed, where the passage of time is measured not by clocks, but by the gradual thickening of the tree line and the return of the migratory birds.

About This Potomac Map Page

This page provides an embedded street and satellite map of Potomac, Maryland. Coordinates: 39.013332, -77.193579. 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 Potomac includes the ZIP code (20854, 21502, 20817), telephone area code (410, 443, 301, 240), county seat of Allegany County (Cumberland), and school district assignment (Montgomery County Public Schools).

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.
