About this map

The High Sierra divide at Sonora Pass serves as a meeting point for three counties and two major national forests. This 2018 survey documents the headwaters of the Middle Fork Stanislaus River, where high-altitude water management is evident at Relief Reservoir and the glacial bowl of Kennedy Lake. The topography is defined by prominent summits such as Leavitt Peak and Sonora Peak, which stand alongside historical passage points like Saint Marys Pass.

Modern recreation and military utility intersect here, with the Pacific Crest Trail winding through the granite basins past Blue Canyon Lake and Deadman Lake. The eastern section of the map includes a portion of the MWTC Bridgeport training grounds, while lower elevations near Kennedy Meadow and Chipmunk Flat show the transition from the steep canyon walls of Blue Canyon to the more open reaches of Relief Valley.
