1956 Map of Cedar Mtn

USGS Topo · Published 1972

About this map

Arroyo Mocho winds through this section of the Diablo Range along the border of Alameda and San Joaquin counties, defining a landscape of deep canyons and prominent ridges. During the mid-20th century, the region maintained its character as a remote ranching and watershed area, evidenced by the Rancho Los Mochos and the isolated Fourteenmile House. The infrastructure of California’s water history is clearly visible here, as the Hetch Hetchy Aqueduct cuts across the northern terrain, supported by features like the Mitchell Shaft. The map records a transition from high peaks like Mt Wallace and Eagle Mtn down into the complex drainage systems of Corral Hollow and Taylor Canyon. Small-scale mining and exploration are noted through scattered Prospects and Mines, particularly near Cedar Mountain Ridge, while landmarks such as the Buckeye Club and Sweet Springs indicate specific points of local human activity within the vast ridgelines.
