1952 Map of Sly Park
USGS Topo · Published 1962About this map
Jenkinson Lake occupies the center of this terrain, its basin newly defined by the Sly Park Dam as part of the mid-century water management efforts in the Eldorado National Forest. Blue hatching on the map reveals the specific areas destined for submergence by the reservoir, a critical detail for those researching the valley's original floor. The landscape is a network of mid-century industrial activity and forestry, where the Phippen Mill (Site) and numerous mining operations like the Hazel Creek Mine and Blue Gouge Mine speak to the local timber and mineral economy. To the south, the North Fork Cosumnes River and its tributaries, such as Grizzly Creek and Cedar Canyon, cut through the ridges. Remote outposts like the Grizzly Flat Guard Station and Sly Park Guard Sta provide geographic anchors for researchers tracing the early administrative and fire-lookout history of the Sierra foothills.
