1952 Map of Sly Park

USGS Topo · Published 1976

About this map

Jenkinson Lake sits at the heart of this landscape, created by the Sly Park Dam within the Eldorado National Forest. The map documents a rugged section of El Dorado County defined by the steep drainage basins of the Cosumnes River and Sly Park Creek. A legacy of resource extraction is evident in the numerous mining operations scattered across the ridges, including the Mt Hope Mine, Cosumnes Mine, and Hazel Creek Mine. These sites, along with the Grizzly Flat Guard Station and Sly Park Guard Sta, point to the area's dual history of industrial prospecting and federal land management.
