1956 Map of Cedar Mtn

About this map

Arroyo Mocho flows through a series of steep canyons and ridges along the Alameda and San Joaquin county border in this mid-century survey. The landscape is defined by the massive infrastructure of the Hetch Hetchy Aqueduct, which cuts through the northern hills near the Mitchell Shaft. Settlement is sparse, represented by isolated landmarks like Fourteenmile House and the Rancho Los Mochos, alongside the Buckeye Club further south. High peaks such as Cedar Mtn, Mt Wallace, and Sugarloaf Butte provide prominent triangulation points for the survey. This era shows the land as a working ranching and mining environment, with several Mines and Prospects dotting the terrain of Crane Ridge and Man Ridge. Numerous reservoirs and springs, including Sweet Springs, suggest a reliance on managed water sources in this dry upland territory.
