How to Use This Mad River, California Map

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

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.

Mad River occupies a rugged expanse of high country where the earth folds into deep, forested creases and timbered slopes. It lies 35.5 miles east-southeast of Fortuna, CA (from Fortuna, CA: bearing 106°T), and is situated 18.6 miles west-southwest of Hayfork. The landscape is defined by the relentless presence of Six Rivers National Forest, which blankets the terrain in thick timber and dense undergrowth. To the west, the ground rises toward the distant Klamath Mountains, their summits often obscured by the low-hanging haze that settles over the ridges. Near the sharp descent of Tierney Canyon, the land takes on a somber, ancient character, where the light at dusk fractures against the dark needles of fir and pine, turning the valley floor into a pool of violet shadow.

Mad River draws its vitality from the steady, cold flow of its namesake waterway, which carves a path through the heart of the forest. The economy here remains tethered to the slow, deliberate rhythms of the woods, echoing a time when the extraction of timber and the stewardship of the land dictated the tempo of daily existence. Residents look toward the Mad River Trail for a connection to the wilderness, a path that winds through the steep, unforgiving topography of the interior. Life here possesses a quiet, singular gravity, shaped by the isolation of the mountains and the enduring, silent weight of the trees that stand as sentinels over the valley.
