About this map

Arroyo Mocho carves a deep path through this section of the Diablo Range, where industrial utility meets isolated ranch land during the mid-1950s. The presence of the Hetch Hetchy Aqueduct and the Mitchell Shaft highlights the critical infrastructure built to move water across the state. This landscape is defined by its dramatic ridges, including Cedar Mountain Ridge and Eylar Mountain Ridge, which hem in a network of canyons and gulches.

Local history is preserved in landmarks such as the Fourteenmile House and Rancho Los Mochos, indicating early settlement patterns in the hills of Alameda and San Joaquin counties. Resource extraction is evident through scattered Mines and Prospects found near Cedar Mtn. Dozens of small catchments and a Water Tank at Sweet Springs underscore the necessity of water management in this high-elevation terrain, which rises to peaks like Mt Wallace and Eagle Mtn.
