Explore Post Mountain, 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 Post Mountain, 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 Post Mountain.
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.

Post Mountain occupies a rugged expanse of high-elevation terrain where the air thins into a crisp, pine-scented clarity. It lies 45.1 miles west-southwest of Redding, CA (from Redding, CA: bearing 256°T), and is situated 9.3 miles south-southwest of Hayfork. Post Creek carves a serpentine path through the landscape, its cold, clear waters carving deep into the earth of Road Gulch before meandering past the slopes that define the local topography. Dense timber stands as a silent sentinel in the Trinity National Forest, which envelopes the landscape in a vast, verdant hold. During the height of the summer, the grasses turn to a brittle, gilded straw, catching the slanted afternoon light that seems to hold the heat of the day long after the sun has slipped behind the distant, jagged silhouettes of the Klamath Mountains.
Historical rhythms in Post Mountain have long been dictated by the extraction of timber and the slow, deliberate pace of mountain life. The economy remains tethered to the land, drawing from the surrounding woods and the challenging, unyielding soil that demands a particular grit from those who choose to reside here. Far from the frantic pulse of urban centers, the local experience is defined by the Tule Divide Trail, which offers a solitary passage through the wilderness, and the quiet, hidden presence of Hell to Find Lake, resting in its remote basin eight miles away. Life here moves with the deliberate, seasonal crawl of the wild, where the isolation is not a lack of connection but a profound, quiet alignment with the geology and the enduring, weathered character of the forest.

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.
