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.

Four Corners emerges from the rolling Piedmont landscape where the earth holds a quiet, heavy stillness. It lies 1.3 miles south-southeast of Kemp Mill, MD (from Kemp Mill, MD: bearing 165°T), and is situated 8.7 miles north of Washington. The Long Branch carves a steady, narrow path through the local terrain, its waters moving with a deliberate urgency toward the broader regional drainage. Beyond the immediate tree line, the land rises in subtle swells that suggest the distant, hazy blue silhouettes of the Appalachian Mountains far to the west. Residents often find their way toward the Blair Lp, a public space that offers a respite of deep grass and shaded clearings. During the transition of seasons, the light here turns a pale, translucent gold that catches the edges of the Soapstone Valley, illuminating the quiet geography of Four Corners with remarkable clarity.

Four Corners maintains an economy rooted in the steady, modest labor that characterizes this stretch of the Maryland interior. The early development of the site relied upon the movement of goods through the corridors that bisect the region, fostering a culture of self-reliance and measured growth. Small-scale manufacturing and service-oriented businesses now provide the primary pulse of the local industry, keeping the pace of commerce linked closely to the needs of the immediate surroundings. Economic life here remains unpretentious, favoring long-standing family ventures over the volatile shifts of larger urban markets. The persistence of these local enterprises ensures that Four Corners remains a place where the work performed each day is visible and grounded.

Cultural life in Four Corners thrives on the quiet continuity of local traditions and the shared familiarity of its residents. The White Horse Trail provides a common artery for those seeking movement through the woods, serving as a social touchstone for hikers and neighbors alike. While the town remains modest in scale, the community often gathers for seasonal events at the Blair Lp, which serves as the primary stage for local interaction. While many notable figures have passed through the region over the decades, the character of the place is defined more by the collective spirit of its people than by the legacy of any single individual. The atmosphere in Four Corners is one of steady, deliberate existence, where the passage of time is marked not by grand gestures, but by the slow, reliable turn of the seasons across the fields.

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 Montgomery County (Rockville), 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.
