About this map

Six Rivers National Forest blankets this corner of the California Coast Ranges during the late 1970s, where the Van Duzen River and Mad River carve through the mountain terrain. The small community of Dinsmore serves as a local hub, supported by the Dinsmore-Humboldt County Airport and a nearby Trailer Park. Educational life for the surrounding valleys is centered at the Van Duzen School and Southern Trinity High School, located near a Radio Facility and the Mad River Ranger Station.

The landscape is defined by high ridges and peaks, including Buck Mountain, Tierney Peak, and Red Mountain, interwoven with a network of jeep trails. These paths connect isolated landmarks like Buck Rock and Browns Rock. Resource extraction and infrastructure are visible through several burners, a Gravel Pit, and a pipeline that traverses the northern reaches of the quadrangle near Sulphur Valley.
