1979 Map of Devils Nose

About this map

The Mokelumne River and its various forks define this portion of the Sierra Nevada foothills during the late 1970s. The landscape is a complex network of hydroelectric infrastructure and resource management, evidenced by the presence of the Tiger Creek Reservoir, Tiger Creek Forbay, and Tiger Creek Regulator Res. A system of an Aqueduct, Siphon, and Flume connects these water bodies to a Powerhouse on the river banks, illustrating the mid-century engineering required to harness mountain runoff for power. Within the boundaries of the Eldorado National Forest and Stanislaus National Forest, the map reveals early logging and mining traces, such as a Prospect and several Quarry sites. Settlement is sparse, represented by named locations like Bruce Crossing and Hunter Flat, while remote access is maintained via the Blue Mountain Road and various unnamed Jeep Trails that traverse high points like Bald Mountain and Devils Nose.
