How to Use This Petersville, Maryland Map

This interactive map shows the street layout and satellite imagery for Petersville, 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 Petersville.

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.

Petersville emerges as a quiet convergence of agrarian tradition and the slow, rhythmic pulse of the Maryland Piedmont. It lies 9.6 miles west of Ballenger Creek, MD (from Ballenger Creek, MD: bearing 259°T), and is situated 2.4 miles north-northeast of Brunswick. The landscape surrounding Petersville unfolds in expansive, cultivated fields that stretch toward the distant, hazy silhouettes of the Blue Ridge Mountains, a jagged line against the western horizon that anchors the entire view. Beneath the canopy of ancient hardwoods, the land slopes gently toward the banks of Little Catoctin Creek, where the water moves with a deliberate, cooling persistence through the undergrowth. Othello Regional Park provides a local sanctuary where the silence of the woods is interrupted only by the rustle of dry leaves and the sharp, sudden call of a hawk circling above the open meadows.

History lingers here in the weathered stone foundations and the sturdy, unadorned architecture of homes that have witnessed generations of seasonal harvests. The economy of Petersville remains deeply tethered to the soil, defined by the steady labor of those who manage the surrounding tracts and maintain the modest, functional beauty of the countryside. Beyond the immediate fields, the terrain rises toward the rugged elevation of the Loudoun Heights Trail, offering a vantage point that reveals the vast, patterned expanse of Pleasant Valley. Even as the sun lowers, casting long, amber shadows across the fence lines, the atmosphere retains a grounded, singular clarity that distinguishes Petersville from the hurried pace of the modern world.

About This Petersville Map Page

This page provides an embedded street and satellite map of Petersville, Maryland. Coordinates: 39.34649, -77.610823. 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 Petersville includes the ZIP code (21758), telephone area code (410, 443), county seat of Frederick County (Frederick), and school district assignment.

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.
