1952 Map of Sly Park

About this map

Jenkinson Lake serves as a focal point in this portion of the Eldorado National Forest, where the topography reflects a landscape shaped by water management and mid-century resource extraction. The map records a complex network of canyons and ridges, including Sturdevant Ridge and Baltic Ridge, carved by the North Fork Weber Creek and the Steely Fork Cosumnes River. A legacy of Gold Country enterprise is evident in the cluster of specialized mining sites such as the Hazel Creek Mine, Blue Gouge Mine, and Eagle King Mine. These operations, scattered among the peaks, suggest a era of deep-mountain industry that predates the recreational focus of Snowline Camp and Happy Valley. Notable infrastructure for the period includes the Sly Park Dam and the Sly Park Guard Sta, illustrating the transition from raw wilderness to a managed national forest system during the early 1950s.
