About this map

The boundary between San Joaquin and Stanislaus counties bisects a landscape defined by industrial water transport and agricultural development. Central to this area is the massive infrastructure of the California Aqueduct, the Hetch Hetchy Aqueduct, and the Delta-Mendota Canal, which traverse the flat valley floor. In the northern reaches, the Rising Sun School and the settlement of Solyo mark the local community centers near El Pescadero (Grimes).

To the southwest, the terrain rises sharply into the hills toward Mt Oso, where the rugged topography is carved by deep drainages like Ingram Canyon and Rocky Ford Canyon. This transition from the engineered waterways of the valley to the natural springs of the upland, such as Martin Spring and Cedar Spring, illustrates the dual nature of California's central valley water management and its relationship to the surrounding foothills.
