2022 Map of Swim Ridge

About this map

The convergence of three major federal lands defines this mountainous corridor of Trinity County, where the boundaries of Trinity National Forest, Six Rivers National Forest, and Mendocino National Forest meet. This terrain is carved by the N Fork Mad River, which serves as a primary drainage for the surrounding ridges. The hydrology of the area is further characterized by Happy Camp Cr and the localized Happy Camp Spring in the northern reaches, while Barry Cr and Frout Cr drain the southwestern and northern slopes respectively. The map provides a precise look at the wilderness management boundaries and the complex watershed of the California Coast Ranges as they appeared in the early 21st century.
