1977 Map of Dinsmore

USGS Topo · Published 1978

About this map

The Van Duzen River and Mad River cut through the heavily timbered sections of the Six Rivers National Forest along the Humboldt and Trinity county line. This 1970s landscape centers on the small community of Dinsmore, featuring the Dinsmore-Humboldt County Airport and essential mountain infrastructure like the Mad River Ranger Station. The settlement pattern reflects the area's role as a regional hub for education and communication, anchored by the Southern Trinity High School and Van Duzen School, alongside the Low Gap Radio Facility perched near Mad River Ridge.
