1955 Map of Cisco Grove

About this map

Cisco Grove and the high Sierra Nevada landscape are documented here during a period of mid-century infrastructure expansion. The Southern Pacific railroad and U. S. 40 parallel the South Yuba River, marking a critical transportation corridor through the mountains. This map captures the intersection of recreation and industry, showing the Carlisle Mine and a Microwave Relay Station alongside youth organizations like the Marin-Sierra Boy Scout Camp and 4H Club Camp. The terrain is characterized by dramatic elevation shifts, from the heights of Signal Peak and Red Mountain down to the basins of Lake Valley Reservoir and numerous alpine lakes such as Crystal Lake and Huysink Lake. The presence of a Ranger Station at Big Bend and the Gaging Station reflects the active management of the Tahoe National Forest at this time.
