1979 Map of Sonora Pass

About this map

Stanislaus National Forest and the Toiyabe National Forest converge at the high crest of the Sierra Nevada, marking a landscape defined by rugged high-altitude terrain and the historical transit routes through the mountains. Centered around Sonora Pass and Saint Marys Pass, the map documents the seasonal activity centers at Kennedy Meadow and Chipmunk Flat, where a Grave and a Gaging Station indicate the small human footprint in this wilderness area. The region is a hydrographic crossroads, with water flowing toward the East Fork Carson River and the Tuolumne River system via Relief Reservoir.
