How to Use This Herlong, California Map

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

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 Herlong, California

Herlong is a locality in Lassen County, California, United States. It is a small community with a population of 237. The population density is 54.9 people per km². Herlong is located at 40.1435°N, 120.1347°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 96113.

Herlong occupies a vast, high-desert expanse where the horizon stretches toward a distant, hazy silhouette of the Sierra Nevada. It lies 33.2 miles southeast of Susanville, CA (from Susanville, CA: bearing 124°T), and is situated 33.1 miles north-northwest of Cold Springs. The landscape is defined by a rigorous, sun-bleached clarity, where the brush-covered plains give way to the alkaline flats near Honey Lake, three miles to the east. Long Valley Creek meanders through the scrub two miles from the center, a thin ribbon of resilience in a basin that feels ancient and indifferent to the passage of time. The air here holds a sharp, dry clarity that brings the distant, jagged peaks into startling focus, while the sagebrush sighs under the relentless, cooling winds that sweep across the valley floor at dusk.

Herlong emerged from the exigencies of the twentieth century, anchored by the development of the Sierra Army Depot, which remains the primary engine of the local economy. The architecture reflects this utilitarian origin, with rows of housing standing in quiet relief against the wide, open sky of the Doyle Wildlife Area, which envelopes the perimeter. Life in Herlong moves in synchronization with the operations of the facility, maintaining a steady, disciplined pulse that contrasts with the wild, unkempt beauty of the surrounding wilderness. Travelers heading toward the more forested reaches of the Little Last Chance Canyon Special Interest Area often pass through this corridor, catching only a fleeting glimpse of a place where the history of defense and the quiet persistence of the high desert intersect.

About This Herlong Map Page

This page provides an embedded street and satellite map of Herlong, California. Coordinates: 40.143514, -120.134652. 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 Herlong includes the ZIP code (96113), telephone area code (530), county seat of Lassen County (Susanville), and school district assignment (Fort Sage 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.
