About this map

The high Sierra Nevada landscape along the Southern Pacific rail line is documented here during the mid-1950s. The corridor following the South Fork Yuba River serves as the primary artery for travel and recreation, connecting small mountain communities like Cisco Grove, Rainbow, and Big Bend. This area of the Tahoe National Forest shows a mix of utility and leisure, with infrastructure like the Microwave Relay Sta and various snowsheds alongside seasonal destinations such as the Marin-Sierra Boy Scout Camp and the 4H Club Camp.

Resource management and high-altitude geography define the terrain, from the Lake Valley Reservoir to the peaks of Signal Peak and Old Man Mtn. The map highlights the intersection of industrial transport and mountain life, where the Carlisle Mine and timber-related flats like Woodchuck Flat sit near the many alpine lakes, including Salmon Lake and the Loch Leven Lakes. The survey also marks the boundary between Nevada Co and Placer Co as it crosses the rugged ridges.
