About this map

Black Rock Mtn Lookout stands as a primary vantage point in this mid-century survey of the California wilderness, where the boundaries of the Trinity National Forest, Six Rivers National Forest, and Mendocino National Forest converge. The landscape is defined by the deep canyons of the South Fork Trinity River and the Middle Fork Eel River, separated by a complex network of high ridges including Jones Ridge and Fisher Ridge.

Evidence of early 20th-century resource extraction and remote habitation is scattered throughout the drainages, from the Bonanza Mine and Trout Creek Mine to the ruins at Double Cabins and Jensen Cabin. The map documents a rugged interior economy based on forestry and isolated ranching, anchored by locations like Travis Ranch and the Indian Dick Guard Station. It captures a transition period for the Yolla Bolly - Middle Eel Wilderness Area before the further consolidation of forest management infrastructures.
