Explore Angwin, 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 Angwin, 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 Angwin.
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.

Angwin sits atop a high, forested plateau where the air holds a persistent, cooling stillness even as the sun bleaches the surrounding lowlands. It lies 17.1 miles east-northeast of Santa Rosa, CA (from Santa Rosa, CA: bearing 57°T), and is situated 5.0 miles north-northeast of Saint Helena. Conn Creek carves a path through the landscape nearby, its seasonal flow shaping the rugged terrain that slopes away toward the depths of Mill Valley. The horizon is defined by the distant silhouette of the Coast Ranges, which catch the violet light of evening and anchor the expanse of oak savanna and timbered ridges. Within a short distance, the moisture-rich canopy of the PUC Demonstration and Experimental Forest provides a dense, verdant contrast to the sun-drenched clearings, while the occasional sound of rushing water echoes from Linda Falls, a quiet sanctuary carved into the rock.
Angwin maintains a rhythm dictated by the scholarly pursuits of its resident university and a history deeply rooted in intentional, quiet development. The local economy and daily pulse are tethered to the educational institution, creating an atmosphere where the pursuit of knowledge often outweighs the frantic pace of the outside world. Residents might spend their afternoons walking the quiet stretches toward Lake Henne or venturing out toward the Redwood Trail, finding a deliberate pace that ignores the industrial sprawl found elsewhere. The character of Angwin remains defined by this intersection of academic life and the physical demands of the plateau, where the soil and the silence of the woods exert a steady, grounding influence on everyone who resides here.

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.
