Explore Big Pool, 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 Big Pool, 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 Big Pool.
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.

Big Pool occupies a quiet stretch of land where the earth settles into a patient, terrestrial stillness far removed from the restless motion of the coast. It lies 13.7 miles west of Halfway, MD (from Halfway, MD: bearing 271°T), and is situated 8.0 miles northwest of Falling Waters. The landscape here is defined by the deliberate, glassy expanse of Big Pool itself, a limestone-bottomed body of water that mirrors the changing moods of the sky with a clarity that seems to hold the light long after the sun has dipped toward the distant Appalachian Mountains. A sense of permanence clings to the ground, where the Chesapeake and Ohio Canal carves a linear path through the terrain, its old towpath now serving as a primary artery for the Western Maryland Rail Trail. Travelers moving through this corridor often remark on the particular density of the afternoon air, which feels heavy with the scent of damp soil and the cool, mineral sharpness rising from the water’s edge.
History in Big Pool is measured not in decades, but in the slow accumulation of sediment and the persistent endurance of the canal, which once served as a vital artery for the region’s agricultural economy. The legacy of that industrial era lingers in the stonework of the locks and the way the nearby basin of Bear Pond Hollow suggests a deeper, more rugged topography lurking just beyond the immediate horizon. Life in Big Pool maintains a deliberate pace, governed by the cycles of the seasons and the quiet maintenance of the trail that draws cyclists and walkers to traverse the path once occupied by mule teams and canal boats. It is a place where the economy has shifted from the frantic transit of coal and grain to a more contemplative stewardship of the landscape, allowing the quiet rhythms of the inland woods to dictate the character of the day.

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.
