1950 Map of Robbs Peak

USGS Topo · Published 1987

About this map

Eldorado National Forest dominates this landscape, showing a mid-century network of remote outposts and water management infrastructure. The Georgetown Divide Ditch snakes through the high country, illustrating the vital role of water transport in this part of the Sierra Nevada. High points like Silver Hill and Robbs Peak, featuring the Robbs Peak Lookout, provide vantage points over the Rubicon River and its various forks. Notable settlements and stopping points include the well-known Uncle Toms Cabin and Ditch Camp, while the southeastern corner is marked by the presence of the Union Valley Reservoir and an associated substation. This survey, based on 1948 photography with 1973 revisions, captures the area during a period of transition as forest management and utility infrastructure like the Hardess Guard Sta became more established.
