About this map

Pacific Crest National Scenic Trail winds through the high elevation border between Klamath National Forest and Shasta National Forest in this 2018 survey. The landscape is defined by the headwaters of the Trinity River and a dense network of alpine lakes and creeks. These water bodies, including Tangle Blue Lake, Big Bear Lake, and the diminutive Wee Bear Lake, are fed by several drainages such as Bear Cr and Horse Cr.

Relatively level terrain is rare in this part of the Klamath Mountains, found primarily at small clearings like Sunflower Flat and Sunny Flat near the riverbanks. The map documents the boundary between Siskiyou and Trinity counties as it follows the high ridges. This modern topographic study records the vital watershed geography where Ramshorn Cr and Davis Cr contribute to the regional river system, highlighting the area's role as a protected wilderness corridor.
