1950 Map of Slate Mtn

USGS Topo · Published 1976

About this map

The Slate Mountains rise above the deep canyons of the South Fork American River in this 1950s era survey, later revised to reflect mid-century landscape changes. This corner of the Eldorado National Forest shows a transition from resource extraction to managed land use, evidenced by the Slate Mtn Mine (Inactive) and the Blodgett Experimental Forest. Local education and community life are anchored at the Mosquito District Sch and a nearby Cem, while agricultural footprints remain at Morton Ranch. The map captures the infrastructure of the era, from the Slate Mtn Lookout watching over the timber to the Finnon Res spillway. Traces of earlier industrial history appear in the dismantled railroad grades and former mining sites like the Badger Hill Mine.
