1970 Map of San Gorgonio Mtn

USGS Topo · Published 1988

About this map

San Gorgonio Wilderness and its high-elevation terrain dominate this landscape, which was updated in 1988 to reflect contemporary features such as the Radio Facility and Diversion Dam. The map captures the rugged interior of the San Bernardino National Forest, where steep drainages like Mill Creek Canyon and Sawmill Canyon converge. Local history and resource extraction are marked by the Mill Creek Mine (Quarry) and the Penstock Powerhouse near Big Oaks Flat.
