The Mattole River headwaters and the rugged interior of southern Humboldt County define this late-1960s landscape. Small settlements like Briceland and Whitethorn anchor a terrain dominated by significant ridges and deep creek valleys. The presence of the Whitethorn Sch and the Thorn Fire Control Station suggests a remote but managed wilderness, while a single Gas Well near Briceland points to localized resource extraction. To the west, the boundary of the King Range National Conservation Area marks the edge of the coastal wilderness, separated from the interior by the high elevations of Telegraph Ridge. The map captures a moment when travel through these hills relied on routes like Shelter Cove Road and Briceland Rd, connecting isolated flats and junctions such as Johnson Flat and Thorn Junction.
