How to Use This Alleghany, California Map

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

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 Alleghany, California

Alleghany is a locality in Sierra County, California, United States. It is a small community with a population of 30. The population density is 33.2 people per km². Alleghany is located at 39.4696°N, 120.8433°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 95910.

Alleghany maintains a quiet existence within the rugged, steep-walled confines of Smiths Flat, where the North Fork Kanaka Creek carves a persistent path through the dense, timbered landscape. It lies 20.9 miles northeast of Grass Valley, CA (from Grass Valley, CA: bearing 34°T), and is situated 17.1 miles north-northeast of Nevada City. The air here carries the scent of pine and damp earth, a consequence of the dense canopy provided by the Tahoe National Forest that surrounds the settlement in every direction. Sunlight struggles to penetrate the deep ravines, casting long, sharp shadows that shift across the uneven terrain as the day progresses. The rugged isolation of the landscape discourages casual passage, leaving the land to exist in a state of deliberate, quiet stillness that is interrupted only by the rhythmic, cold rush of the nearby creek.

Alleghany emerged from the fever of gold extraction, its history written in the tunnels and quartz veins that once defined the local economy and drew prospectors to this unforgiving terrain. While the fervor of the mines has long since faded into a slower, more deliberate pace of life, the remnants of that industry remain visible in the weathered structures that cling to the hillsides. Travelers seeking a connection to the wilderness often find their way toward the Sunshine Trail, which offers a narrow window into the surrounding forest, far removed from the bustle of the distant valleys. Though New Bullards Bar Reservoir lies over a dozen miles away, the identity of Alleghany remains tethered to the high, forested ridges of the Sierra Nevada, which loom on the horizon as a constant, silent observer of the life unfolding below.

About This Alleghany Map Page

This page provides an embedded street and satellite map of Alleghany, California. Coordinates: 39.469618, -120.843279. 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 Alleghany includes the ZIP code (95910), telephone area code (530), county seat of Sierra County (Downieville), and school district assignment (Sierra-Plumas Joint Unified 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.
