Explore Green Valley, 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 Green Valley, 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 Green Valley.
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.

Green Valley emerges from the quiet intersection of verdant slopes and the persistent, winding course of Bennett Creek. It lies 3.1 miles east-southeast of Urbana, MD (from Urbana, MD: bearing 112°T), and is situated 9.4 miles southeast of Frederick.
The water of Bennett Creek carves a meditative path through the landscape, providing a constant, rhythmic presence that defines the local topography. To the west, the distant silhouettes of the Blue Ridge Mountains offer a stoic boundary against the evening sky, their jagged peaks softened by the hazy, violet light of dusk. The land itself shifts into a series of gradual, earth-bound swells that support a dense canopy of hardwoods, particularly as one nears the protected acreage of Litttle Bennett Regional Park. A short distance away, the quiet waters of Chevy Chase Lake mirror the shifting colors of the canopy, holding the stillness of the afternoon within their banks. The air here carries the scent of damp loam and cooling stone, a sensory reminder that Green Valley remains firmly rooted in the interior geography of the state.
Green Valley has matured through the slow accretion of agricultural labor and the steady pulse of modest commerce that followed the early settlers. The local economy relies on a blend of professional services and small-scale enterprise, reflecting a transition from the labor-intensive farming of the previous century to a more modern, service-oriented framework. Industrious residents continue to shape the character of the region, favoring a pace of life that prizes consistency and the quiet maintenance of property. The legacy of these industrious roots is visible in the well-tended fences and the functional architecture that dots the landscape, serving as a quiet witness to the generations that have worked this soil. While the rhythm of trade evolves, the fundamental reliance on the land and its resources remains a constant, grounding force for everyone who calls Green Valley home.
Cultural life in Green Valley unfolds with an understated grace, favoring private gatherings and community observances over the clamor of larger metropolitan centers. Residents often congregate at local landmarks to mark the change of seasons, finding significance in the simple rituals of the calendar year. While the area avoids the fame of high-profile personalities, it fosters a community where the focus remains on the integrity of the individual and the strength of neighborly ties. The proximity to Litttle Bennett Regional Park provides a communal space for those who seek the solace of the outdoors, allowing for a deep connection to the regional flora and fauna. In every season, the atmosphere remains one of measured reflection, where the quality of the light at sunset seems to pause, inviting a moment of stillness before the day concludes.

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.
