Explore Greenhorn, 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 Greenhorn, 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 Greenhorn.
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.

Greenhorn occupies a quiet expanse of rugged terrain where the persistent flow of Estray Creek carves a path through the earth. It lies 35.7 miles south of Susanville, CA (from Susanville, CA: bearing 188°T), and is situated 8.1 miles east-southeast of East Quincy. The air here holds a crisp, high-altitude clarity, carrying the scent of pine needles and damp soil from the surrounding Plumas National Forest. To the east, the horizon is dominated by the distant, jagged silhouette of the Sierra Nevada, while the lower elevations transition into the expansive, hushed terrain of Long Valley. The light at dusk settles over the landscape in long, amber fingers, illuminating the shifting textures of the woodland and the persistent, rhythmic trickle of the creek as it winds past the roots of ancient trees.
Greenhorn preserves the echoes of a nineteenth-century mining legacy, a history etched into the very gravel and soil that early prospectors once turned in search of fortune. Today, the economy remains tethered to the land and the quiet industry of those who manage the resources of the Plumas National Forest, favoring a pace of life dictated by the seasons rather than the clock. For the occasional traveler drawn to the region, the nearby Bachs Ridge Trail offers a passage into the deeper wilderness, while the waters of Lake Davis provide a still, reflective mirror for the sky just a short distance away. Life in Greenhorn moves with an intentional, steady gravity, defined by the enduring presence of the timbered slopes and the cold, clear vitality of the mountain water.

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.
