2018 Map of Ciervo Mountain

About this map

Ciervo Mtn and the Ciervo Hills dominate this portion of the Diablo Range, marking the rugged transition toward the western edge of the San Joaquin Valley. This 2018 survey highlights a landscape defined by sharp elevation changes and seasonal watercourses, where deep canyons like Arroyo Hondo, Arroyo Venado, and Arroyo Leona carve through the arid terrain. The map documents vital water sources in this dry environment, including Ciervo Spring, Borreguero Spring, and Harris Spring. Along the eastern boundary, Monocline Ridge provides a distinct geological border overlooking the Central Valley. Evidence of historic land use and boundary divisions is clear through the Township and Range lines and the San Carlos Bolsa area, illustrating the intersection of natural topography and administrative surveying in Fresno and San Benito counties.
