Explore Big Bend, California, 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 Bend, California. 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 California 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 Bend.
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 Bend occupies a low, salt-brined expanse where the Pacific light bleeds into the horizon, casting long, bruised shadows across the marshy flats. It lies 3.8 miles south of Sonoma, CA (from Sonoma, CA: bearing 183°T), and is situated 9.5 miles east of Petaluma. The landscape remains defined by the persistent drift of fog that rolls inward, dampening the golden grasses and cooling the air as it pushes toward the distant, hazy silhouettes of the Coast Ranges. Water dominates the physical character of Big Bend, with the narrow, winding course of Fowler Creek carving through the silt just a mile away, feeding the quiet, brackish stillness of Goose Lake. This proximity to the brine gives the atmosphere a sharp, metallic edge, a constant reminder that the restless tides of McNear Channel exert a silent, gravitational pull upon the soil and the life that clings to it.
History here is written in the slow reclamation of the land by the Napa-Sonoma Marshes Wildlife Area, a sprawling sanctuary that absorbs the quietude of the surrounding Sonoma Valley. Economic vitality in Big Bend has long been tethered to the rhythms of these wetlands, shifting from the early, rugged efforts of reclamation to a modern existence that favors conservation and the seasonal migrations of waterfowl. The nearby presence of Skaggs Island serves as a lonely sentinel in the marshes, a testament to the isolation that defines the local character. Life here moves with a heavy, deliberate pace, far removed from the frantic pulse of the urban centers, leaving residents to walk the quiet paths and observe the way the light catches the reeds at dusk, turning the gray water into a sheet of hammered silver.

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.
