How to Use This Byron, California Map

This interactive map shows the street layout and satellite imagery for Byron, 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 Byron.

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.

Byron is a locality in Contra Costa County, California, United States. It has a population of approximately 1,140. The population density is 67.5 people per km². Byron is located at 37.8756°N, 121.6421°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 94514.

Byron occupies a flat, sun-drenched expanse where the air holds the dry, expectant heat of the interior, yet carries a faint, salt-tinged memory of the ocean seventeen miles to the west. It lies 3.5 miles southwest of Discovery Bay, CA (from Discovery Bay, CA: bearing 216°T), and is situated 5.5 miles southeast of Brentwood. The horizon is dominated by the distant, hazy silhouette of the Coast Ranges, while the immediate landscape is defined by a low, rhythmic sweep of earth that descends toward the marshy margins of Sand Bay. Brushy Creek meanders through the periphery, its seasonal path tracing a quiet line through the fields, while the nearby Los Vaqueros Watershed offers a protected sanctuary of high grasses and open sky. To the north, the water of Clifton Court Forebay glints under the heavy Pacific light, a steady, man-made presence that anchors the surrounding agricultural grid against the persistent, shifting dust of the valley floor.

Byron emerged from the intersection of mineral springs and fertile soil, its character forged by a history of restorative waters and the relentless labor of the harvest. The economy remains tied to the pulse of the land, where the seasonal cycle of growth and dormancy dictates the pace of daily affairs, and the shadow of Briones Valley keeps a cool watch over the local fields. Widdows Island sits as a quiet, isolated landmark in the nearby waters, a relic of a geography shaped by the constant press of tides and the reclamation of the soil. Life here maintains a singular focus, shaped by the interplay of the deep, subterranean fault lines and the vast, Mediterranean-toned sky that seems to expand with every passing hour of the afternoon.
