How to Use This Knightsen, California Map

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

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.

About Knightsen, California

Knightsen is a locality in Contra Costa County, California, United States. It has a population of approximately 1,596. The population density is 73.7 people per km². Knightsen is located at 37.9624°N, 121.6486°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 94548.

Knightsen spreads across a flat, expansive horizon where the golden light of the Pacific coast filters through a thin, persistent haze. It lies 3.0 miles north-northeast of Brentwood, CA (from Brentwood, CA: bearing 31°T), and is situated 7.9 miles east-southeast of Antioch. The earth here possesses a heavy, dark composition, shaped by the slow, meandering path of Marsh Creek as it carves through the low-lying terrain. To the west, the distant, hazy silhouette of the Coast Ranges anchors the view, while the nearby landscape remains defined by wide, open fields that transition into the marshy expanse of Big Break. The air carries a salt-touched clarity, particularly when the fog drifts inward, softening the edges of the flatlands and lending a muted, silver quality to the late afternoon. Beyond the immediate reach of the fields, the waters of Clifton Court Forebay and the proximity of Bethel Island define the fluid boundary between solid ground and the encroaching tide.

Knightsen maintains a quiet, agrarian character that honors a history rooted in the cultivation of the soil and the steady labor of the harvest. The economy remains tethered to the land, with local growers tending to orchards and crops that thrive in the rich, alluvial sediment of Lone Tree Valley. Daily life moves with the deliberate pace of the seasons, far removed from the frantic pulse of larger centers, yet connected to the regional flow of commerce and transport. Residents often find respite in the quiet trails of Marsh Creek Glen Park, a space that preserves the natural quietude of the basin. This dedication to the land creates a distinct atmosphere, where the silence of the evening is broken only by the low hum of distant machinery or the rustle of dry grass under a wide, darkening sky.

About This Knightsen Map Page

This page provides an embedded street and satellite map of Knightsen, California. Coordinates: 37.962426, -121.64858. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Knightsen includes the ZIP code (94548), telephone area code (510), county seat of Contra Costa County (Martinez), and school district assignment (Liberty Union High School District).

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.
