About this map

Emigrant Wilderness and the Stanislaus National Forest define this high-altitude landscape in the Sierra Nevada. The terrain is marked by the sharp rise of Cooper Peak and Castle Rock, which guard the passage at Eagle Pass. This map illustrates a complex network of high-country meadows and glaciated basins, where features like Horse and Cow Meadow, Coyote Meadows, and Whitesides Meadow provided seasonal forage and vital landmarks for early travelers.

Water systems are central to the area's character, with the South Fork Stanislaus River and Cherry Creek carving through granite. The presence of the Y Meadow Dam reflects human modification of these remote waters, while numerous subalpine lakes, including Bear Lake, Leopold Lake, and Chewing Gum Lake, dot the Emigrant Wilderness. Dozens of named peaks, canyons, and meadows such as Toms Canyon and Groundhog Meadow are connected only by a network of Pack Trails, underscoring the primitive and preserved nature of this portion of Tuolumne County.
