1956 Map of Cedar Mtn

About this map

The Hetch Hetchy Aqueduct cuts through the northern reaches of this territory, where the infrastructure of water transport meets the industrial history of the Mitchell Shaft. The landscape is defined by the heavy ridgelines of Crane Ridge and Mitchell Ravine, populated by isolated landmarks like the Fourteenmile House and the Buckeye Club. For genealogists and local historians, the map preserves the location of Rancho Los Mochos and numerous Mines and Prospects scattered across the upland slopes. The drainage patterns of Arroyo Mocho and Arroyo Valle provide a natural framework for understanding early land use in this part of Alameda and San Joaquin counties. Survey markers and lookout points, such as the Crane Ridge Lookout and Mt Wallace, highlight the high-elevation vantage points used to manage this territory during the mid-20th century.
