Explore Big Oak Flat, 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 Oak Flat, 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 Oak Flat.
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 Oak Flat occupies a rugged expanse where the earth rises in dry, sun-bleached undulations toward the distant, jagged silhouette of the Sierra Nevada. It lies 32.4 miles east of Oakdale, CA (from Oakdale, CA: bearing 83°T), and is situated 4.7 miles west-southwest of Pine Mountain Lake. Sunlight here possesses a hard, clarifying quality, bleaching the grasses until they turn the color of toasted straw and casting long, sharp shadows across the broken terrain of Grizzly Gulch. To the west, the landscape drops toward the still, deep waters of Don Pedro Reservoir, while the immediate proximity of Cobbs Creek provides a thin, cooling ribbon of riparian growth amidst the pervasive heat. Residents often gather under the open sky at Mary Laveroni Community Park, where the air smells faintly of dry pine needles and the quiet stillness of the inland afternoon is broken only by the occasional rustle of brush.
Gold dust once defined the ambition of Big Oak Flat, drawing thousands to sift through the rocky soil in a frantic, fevered pursuit that left the earth scarred and the local economy permanently altered. Today, the remnants of those mining days exist as weathered stone foundations and half-hidden trails like Ponderosa Way, where the modern pace of life moves with a slower, more deliberate gravity. The local economy has shifted from the extraction of ore to a quiet existence defined by its role as a gateway to the high country, where the rhythm of the day is dictated by the movement of the sun across the foothills. Despite the passage of decades, the character of Big Oak Flat remains tethered to this difficult, beautiful geography, holding fast to a history that is written more in the topography of the land than in the books of men.

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.
