About this map

Silver Mountain (Site) marks a significant point of historical interest in the high Sierras, where three national forests—the Eldorado, Toiyabe, and Stanislaus—converge. This 1970s survey captures the region's legacy of silver extraction, detailing numerous lode locations such as the Lady Franklin, Exchequer, and the Abe Lincoln Mine. The presence of the Isabella Tunnel and Silver Mtn Mineral Mon further emphasizes the intense geological exploration that once defined this area.

Traversing the crest, the Pacific Crest National Scenic Trail winds past high-altitude landmarks like Raymond Peak and Ebbetts Pass. Water resources are abundant, from the North Fork Mokelumne River to alpine basins like Kinney Reservoir and Lower Kinney Lake. The terrain is characterized by a network of drainage systems like Pennsylvania Creek and Silver Creek, which served both the mining operations and the various campgrounds, including Silver Creek Campground.
