2015 Map of Topo Valley

About this map

The San Andreas Fault cuts a diagonal path through this 2015 study of the California Coast Ranges, dividing the complex terrain of the Diablo Range from the valley floor. To the northwest, the edge of Pinnacles National Park borders a landscape of steep drainages like Rosas Canyon and Wildhorse Canyon. The central and eastern portions are dominated by a series of high-altitude basins and valleys, including Horse Valley, Dry Lake Valley, and the elongated Rabbit Valley. In the southeastern corner, the settlement of Bitterwater sits within the Bitterwater Valley along King City Rd, marking a rare point of concentration in a region otherwise defined by ranching land and seasonal water features such as Dry Lake and the San Benito River. This map illustrates the intersection of tectonic geology and the long-established land divisions of the Public Land Survey System.
