About this map

The high Sierra crest of Alpine County serves as a meeting point for the Eldorado National Forest and Toiyabe National Forest, defined by the watershed divide between the West Fork Carson River and the headwaters of the Mokelumne. This 1990s revision documents the commemorative landscape at the pass, including the Snowshoe Thompson Kit Carson historical markers and a nearby grave.

Mineral extraction history is preserved through labels for the Alpine Mine, Alhambra Mine, and Burnside Mine, scattered across high-elevation basins. The map details a robust recreational infrastructure emerging in the late 20th century, from the Pacific Crest National Scenic Trail to established sites like the Upper Blue Lake and Hope Valley campgrounds. Hydrological management is evident at Upper Blue Lake, where the spillway elevation is noted, alongside the natural drainages of Forestdale Creek and Charity Valley Creek.
