About this map

Shasta National Forest dominates this high-altitude landscape along the border of Siskiyou and Trinity counties. The terrain is defined by the steep rises of the Trinity Mountains, where the Pacific Crest National Scenic Trail winds along the eastern ridges near White Ridge and Bear Ridge. This region serves as a critical headwater area, with the E Fork Trinity River flowing in the south and numerous creeks like Mumbo Cr and Sherer Cr draining the slopes.

Legacy mining and geographical markers are scattered throughout the basin, including Cinnabar Gulch, Chrome Gulch, and Willits Ravine. Small alpine lakes such as Picayune Lake, Gumboot Lake, and Mumbo Lake sit in glacial pockets below the summits. Notable peaks and landmarks like Ramshorn Summit and the curiously named The Bedstead provide specific points of interest for those studying the physical history and land-use patterns of the Northern California wilderness.
