2021 Map of Topo Valley

About this map

Bitterwater stands as the primary settlement in this corner of the Diablo Range, situated where the Bitterwater Valley meets the lower slopes of the hills. The landscape is defined by the parallel elevations of the Gabilan Range to the west and the high ridges to the east, creating a corridor of isolated valleys and canyons. Notable features include Pinnacles National Park bordering the western edge and the ephemeral Dry Lake in the north. The drainage of Topo Cr and the San Benito River shape the terrain, while routes like Old Hernandez Rd and Topo Valley Rd provide the only infrastructure through these cattle-ranching and wilderness areas. This map documents a sparsely populated region where traditional land use patterns, such as those at Murphy Flat, persist within a rugged geological framework.
