How to Use This Four Corners, Maryland Map
This interactive map shows the street layout and satellite imagery for Four Corners, 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 Four Corners.
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 Four Corners, Maryland
Four Corners is a locality in Caroline County, Maryland, United States. It has a population of approximately 8,316. The population density is 2193.2 people per km². Four Corners is located at 39.0233°N, 77.0102°W. It observes the Eastern Time (America/New_York) timezone. ZIP codes: 21639, 20901.Four Corners occupies a quiet intersection of Maryland geography where the land transitions from flat, cultivated fields into the subtle, rising contours of the Piedmont. It lies 6.0 miles northeast of Caroline, MD (from Caroline, MD: bearing 52°T), and is situated 6.4 miles north-northeast of Denton. The horizon remains wide and open, holding the distant, hazy silhouette of Opossum Hill to the west as a reminder of the higher ground beyond. A mile from the center, the waters of Little Gravelly Branch carve a modest, persistent path through the soil, feeding the moisture that sustains the surrounding thickets and meadows. At dusk, the light here turns a bruised, singular gold, catching the dust of local roads and illuminating the low, earthy textures of the landscape before the evening chill settles over the fields.
Four Corners maintains a steady, deliberate pace that reflects its long heritage of agricultural commerce and modest regional trade. Residents find recreation at the nearby County Park, a space that preserves the local character without the artifice of more manicured grounds. The economy here moves in step with the seasons, favoring the small-scale enterprise and the quiet labor of those who work the land or commute to the nearby centers of professional life. While the bustle of larger Maryland hubs remains a distant concern, the rhythm of Four Corners is defined by the shifting agricultural cycles and the persistence of its rural roots, where the simple architecture of early colonial settlement still informs the shape of the modern day.

About This Four Corners Map Page
This page provides an embedded street and satellite map of Four Corners, Maryland. Coordinates: 39.023312, -77.010204. 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 Four Corners includes the ZIP code (21639, 20901), telephone area code (410, 443), county seat of Caroline County (Denton), 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.
