About this map

Mendenhall Springs sits nestled within the high ridges of Alameda County, serving as a focal point in a landscape defined by significant water infrastructure and prominent summits. The sprawling Lake del Valle dominates the western portion of the map, featuring Heron Bay and supporting a network of local drainages like Arroyo Mocho and Arroyo Valle. Running through these hills is the critical Hetch Hetchy Aqueduct, a massive engineering feat that carries water toward the San Francisco Bay Area.

Peak baggers and local historians can trace the high points of the Diablo Range, including Rose Peak, Discovery Peak, and Lookout Point. The terrain is marked by distinct ridges such as Crane Ridge, Rocky Ridge, and Wauhab Ridge, which are accessed by winding mountain routes like Mines Rd and Del Valle Rd. Flatlands such as Rose Flat, Shafer Flat, and Hamilton Flat offer a contrast to the steep canyons of Lang Canyon and Williams Gulch.
