The San Antonio Reservoir dominates this portion of the Diablo Range, serving as a central node for regional water infrastructure. The map reveals the complex engineering of the area, featuring both the S Bay Aqueduct and the Hetch Hetchy Aqueduct as they traverse the high ridges and valleys south of Pleasanton. The landscape is defined by sharp elevation changes, from the floor of Sunol Valley to the heights of Maguire Peaks and Apperson Ridge.
