About this map

Cooper Peak rises as a prominent landmark in this high-elevation landscape within the Stanislaus National Forest. The terrain is defined by a series of alpine meadows and glacial basins, including Castle Meadow, Horse and Cow Meadow, and Studhorse Meadow, reflecting a long history of seasonal grazing and water management. The presence of Y Meadow Dam suggests the systematic control of high-country water resources to serve lower elevations, while the Emigrant Wilderness boundary preserves the primitive character of the surrounding peaks and canyons.

Water flows are a central feature of the topography, with the South Fork Stanislaus River and Cherry Creek carving deep drainage patterns through the granite. Numerous high-altitude water bodies, such as Wire Lakes, Jewelry Lake, and Long Lake, are scattered throughout the wilderness area. This 1990 provisional survey documents the trails and drainage networks before modern digital mapping, capturing the specific nomenclature of landmarks like Burst Rock and Lower Relief Valley used by generations of backcountry travelers.
