1950 Map of Slate Mtn

About this map

The South Fork American River carves through the heart of this landscape, anchoring a region defined by early timber and mining operations within the Eldorado National Forest. The presence of a Logging Railroad near Pino Grande and a Dismantled Railroad north of Big X Mtn indicates the area's transition away from rail-dependent industry by mid-century. Evidence of earlier extraction is found at the Slate Mtn Mine and Badger Hill Mine, while a Sawmill and the Mosquito District Sch suggest a settled community near the Finnon Res Spillway. In the north, the Blodgett Experimental Forest sits near high peaks like Sand Mtn. Water management for the region is clearly marked by the American River Intake Dam and various systems including a Plume and Chute near Slab Creek.
