How to Use This Guasti, California Map

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

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 Guasti, California

Guasti is a locality in San Bernardino County, California, United States. It is a small community with a population of 480. The population density is 18.0 people per km². Guasti is located at 34.0650°N, 117.5864°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP codes: 91761, 91743.

Guasti occupies a flat, sun-bleached expanse of the inland basin where the air holds the dry, metallic scent of heated earth. It lies 2.9 miles south of Rancho Cucamonga, CA (from Rancho Cucamonga, CA: bearing 172°T), and is situated 8.9 miles west-southwest of Fontana. To the north, the San Gabriel Mountains rise in a jagged, hazy silhouette against a sky that bleaches to a pale, cloudless white by midday. The landscape is defined by the steady, unyielding passage of Cucamonga Creek, which carves a shallow, gravel-strewn path through the alluvial soil, while the nearby Cucamonga-Guasti Regional Park provides a rare, green respite of still water and manicured grass amidst the vast, industrial sprawl. In the late afternoon, the light here turns a brittle, golden hue, casting long shadows across the concrete arteries that pulse with the constant, low-frequency hum of regional transit.

Guasti carries the weight of a singular ambition, having been founded by Secondo Guasti to become the site of the world’s largest vineyard at the dawn of the twentieth century. Where once endless rows of vines drank from the deep aquifers of the valley, the current economy has shifted entirely toward the logistical machinery of warehouses and sprawling distribution hubs. The historical imprint of the Italian winemaking colony remains in the architecture of the old stone structures, though they now stand in quiet contrast to the modern geometry of loading docks and freight yards. Life in Guasti moves with the rhythmic efficiency of the supply chain, a place where the memory of the harvest is eclipsed by the relentless, organized motion of goods destined for elsewhere.

About This Guasti Map Page

This page provides an embedded street and satellite map of Guasti, California. Coordinates: 34.065011, -117.586441. 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 Guasti includes the ZIP code (91761, 91743), telephone area code (818, 747), county seat of San Bernardino County (San Bernardino), and school district assignment.

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.
