Explore Popponesset Island, Massachusetts, 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 Popponesset Island, Massachusetts. 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 Massachusetts 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 Popponesset Island.
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.

Popponesset Island emerges from the tidal margins as a low-lying expanse of salt marsh and sandy soil, tethered to the mainland by the shifting character of the Atlantic Ocean. It lies 4.6 miles south-southeast of Mashpee, MA (from Mashpee, MA: bearing 166°T), and is situated 8.4 miles east-northeast of Falmouth. The atmosphere here is shaped by the relentless rhythm of the tides, which pull at the fringes of the land and leave behind a saline scent that clings to the beach grass and the weathered pilings of private docks. Beyond the immediate shoreline, the landscape settles into a quiet, flat geography, occasionally punctuated by the presence of Little Thatch Island, a fragile sanctuary that guards the harbor’s edge. The light at dusk softens the sharp edges of the dunes, casting a bruised violet hue over the water that seems to hold the day in a state of suspended, luminous grace.
Popponesset Island retains a quiet history distinct from the bustle of the larger coastal hubs, serving as a seasonal retreat where the economy leans heavily upon the stewardship of the water and the maintenance of summer homes. The influence of the nearby Mashpee River provides a constant, freshwater pulse to the surrounding brackish environment, while Dean Pond sits just enough inland to offer a still, reflective contrast to the restless spray of the coast. Though the distant silhouettes of the Monomoy Island Dunes occasionally haunt the horizon, the focus here remains grounded in the immediate, intimate labor of the tide and the slow, deliberate pace of local life. Residents and visitors alike recognize the island as a place where the clamor of the modern world is muted by the persistent, unhurried motion of the sea, preserving a character that values the solitude of the shoreline over the clamor of inland commerce.

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.
