1986 Map of Tangle Blue Lake

About this map

The Scott Mts dominate this mid-1980s landscape at the border of Siskiyou and Trinity counties, where the high-altitude terrain is divided between the Klamath National Forest and Shasta National Forest. A network of glacial lakes, including Tangle Blue Lake, Big Bear Lake, and Little Bear Lake, feeds into a complex drainage system of creeks such as Tangle Blue Creek and Eagle Creek. The presence of the Pacific Crest National Scenic Trail winding through the western portion of the map indicates the area's significance for long-distance wilderness travel. Scattered historical developments are documented throughout the wilderness, notably the Grand National Mine and isolated outposts like Messner Cabin. Further south along the Trinity River, the map reveals early settlement patterns at Truscott Ranch and Eagle Creek Ranch, situated near broad valley openings like Sunny Flat.
