Explore Jarrettsville, 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 Jarrettsville, 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 Jarrettsville.
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.

Jarrettsville rises from the undulating landscape of the inland plateau, where the East Branch Winters Run cuts a persistent, winding path through the heavy clay and loam of the countryside. It lies 5.0 miles west-northwest of Forest Hill, MD (from Forest Hill, MD: bearing 286°T), and is situated 6.2 miles west-northwest of Harford. Granite outcroppings from the nearby Rock Ridge cast long, jagged shadows as the sun retreats behind the horizon, leaving the air to cool with the scent of damp earth and cooling stone. Two miles to the east, the stillness of Cattail Reservoir reflects the vast, open sky, providing a quiet basin for the local wildlife that traverses the brush. The terrain here is defined by a slow, deliberate gravity, where the elevation rises toward the distant, hazy silhouettes of the landscape, creating a sense of isolation from the frantic pace of the wider world.
Jarrettsville preserves a quiet dignity rooted in the legacy of agricultural industry and the steady, rhythmic labor of generations who shaped these fields. The local economy maintains its connection to the land, moving at the measured speed of seasonal harvests and the daily activity centered around the Jarrettsville Elementary School Fields, which serve as a primary gathering point for the inhabitants. Beyond the reach of the urban sprawl, the character of the region is forged in the silence of the Verdant Valley and the distant, rushing melody of Wiley Falls. Life here is measured by the color of the leaves as they turn in autumn and the way the light catches the frost on the fence lines, offering a grounded existence that values the continuity of the soil over the fleeting trends of modern development.

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.
