1950 Map of Slate Mtn

USGS Topo · Published 1952

About this map

Eldorado National Forest encompasses the rugged terrain of the Slate Mountains in this early 1950s survey. The landscape is defined by the deep canyons of the South Fork American River and its numerous tributaries, including Mosquito Creek and Slab Creek. Industrial history is evident through the presence of the Slate Mtn Mine and Placer Mine, while the Dismantled Railroad and National Chute suggest a transitioning mountain economy. Small settlements and local landmarks like Morton Ranch, Towa Hill, and the Mosquito District Sch provide a glimpse into the isolated communities of the era. Water management is a primary theme, highlighted by the American River Intake Dam and Finnon Res Spillway, which supported local industry and agriculture in the Sierra Nevada foothills.
