2021 Map of Dead Horse Summit

About this map

Shasta National Forest dominates this high-elevation landscape, where the Pacific Crest National Scenic Trail winds through complex terrain marked by landmarks like Mushroom Rock and Bartle Gap. The map documents a rugged volcanic and glacial topography at the northern end of the Sierra Nevada, centered on the Dead Horse Summit and the descent into Dead Horse Canyon. The small settlement of Curtis appears near the summit, serving as a primary point of human activity along the mountain roads. Hydrographic features are prominent, with the upper reaches of the McCloud River and several isolated basins such as Horse Lake and Curtis Lake punctuating the forested ridges. The survey also captures the transition between the Siskiyou and Shasta county lines, illustrating how the wilderness is segmented by both natural drainages like Bull Canyon and administrative boundaries.
