The South Fork Trinity River and the Mad River carve through the high ridges of Humboldt and Trinity Counties, marking a landscape defined by forestry and remote outpost stations in the late 1970s. This survey captures a transitional era where early settlement traces like the Becker Cabin (Site) and Torrey Corrals persist alongside the active infrastructure of the Six Rivers National Forest and Trinity National Forest. Prominent peaks such as Blake Mountain serve as anchor points for a network of fire-lookout stations and pack trails, including the Eightmile Lookout and the Last Chance Trail. Grounded in the topographic reality of the Pacific Northwest, the map details numerous specific water sources and clearings, from Happy Jack Spring to Severin Openings, reflecting a period when seasonal camps like Shell Camp and crossings like Anderson Ford were vital for navigating the steep, drainage-cut terrain.
