Explore Black Hawk, 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 Black Hawk, 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 Black Hawk.
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.

Black Hawk occupies a landscape defined by the quiet persistence of golden grasses and the seasonal cycle of the sun. It lies 7.3 miles north of Pittsburg, CA (from Pittsburg, CA: bearing 6°T), and is situated 9.5 miles north-northwest of Antioch. West Branch Alamo Creek traces a thin, riparian vein through the terrain, offering a cool contrast to the heat that defines the summer months. The horizon is anchored by the distant, hazy silhouettes of the Coast Ranges, which catch the fading light in shades of bruised purple and slate. Nearer to the center of life here, the Black Hills Reservoir holds its stillness, reflecting the vast, cloudless sky that stretches over the dry, inland plains. Mount Diablo State Park serves as the immediate backdrop, where the earth rises in rugged, unyielding contours that govern the flow of wind and shadow.
Black Hawk emerged from the transformation of expansive ranch lands, shifting from agricultural roots into a residential enclave of singular character. The local economy relies less on heavy industry and more on the professional contributions of those who navigate the regional corridors of commerce. Development has followed the contours of the land, respecting the ancient fault lines that pulse deep beneath the topsoil. Residents often observe how the rhythm of the day aligns with the movement of traffic on the nearby freeways, which act as the modern arteries for the surrounding region. The proximity to Devils Slide provides a geological reminder of the instability and power inherent in this shifting basin. Through the decades, the landscape has been shaped by a desire for privacy and a quiet integration with the surrounding oak savanna.
Black Hawk maintains a cultural identity rooted in a measured, deliberate pace of life that prizes both seclusion and connectivity. The architectural spirit of the place draws the eye toward expansive estates that seem to emerge organically from the arid, sun-bleached slopes. Residents frequently spend their leisure time exploring the trails within Mount Diablo State Park, where the scent of dry sage and chaparral fills the air. While the neighborhood remains largely residential, it has served as a home to notable figures such as professional athletes like Jerry Rice, who found a retreat in the quietude of these hills. Community life is defined by a shared appreciation for the stark, dramatic beauty of the California inland, where the light at dusk turns the landscape into a canvas of amber and deep, encroaching gray.

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.
