Explore Saint Marys City, Maryland, 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 Saint Marys City, 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 Saint Marys City.
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.

Saint Marys City occupies a verdant expanse of land where the Saint Marys River flows with a slow, deliberate grace through the quiet interior of the landscape. It lies 5.6 miles south of Lexington Park, MD (from Lexington Park, MD: bearing 169°T), and is situated 6.8 miles northwest of Saint Marys. The terrain here is defined by broad, fertile plains that stretch toward the horizon, punctuated by the subtle depressions of Carthagena Flats and the distant, cooling presence of Langley Hollow. Sunlight filters through the dense canopy of local hardwoods in long, amber shafts, casting soft shadows across the fields that remain largely undisturbed by the frantic pace of modern life. Edgars Ridge marks the western boundary of the world here, a dark, serrated line against the sky that suggests a vast, silent wilderness beyond the reach of the immediate meadows.
Saint Marys City holds the weight of early colonial foundations, serving as a site where the echoes of seventeenth-century governance still linger among the reconstructed timber frames and earthen paths. The economy is inextricably linked to the preservation of these historical narratives and the academic pursuits of the nearby university, which maintains a steady, intellectual pulse throughout the seasons. Life within the protected boundaries of Lp5014 is characterized by a deliberate observation of the past, as students and residents alike move through a landscape that feels suspended in a quiet, contemplative state. Whether observing the muted gray of the winter sky or the vibrant renewal of the spring thaw, those who dwell in Saint Marys City find themselves surrounded by a sense of permanence that honors the labor and the dreams of those who first cleared these woods.

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.
