About this map

Panoche Hills rise along the southwestern edge of this Central Valley landscape, where the flat agricultural plains meet the rising topography of the Coast Ranges. The map illustrates a highly organized grid of irrigation and transport, dominated by the sweeping curve of the Governor Edmond Brown California Aqueduct and the Third Lift Canal. These massive water projects define the local economy, feeding the various reservoirs and wells that dot the ranch land.

Settlement is sparse and centered around working landscapes like Hammonds Ranch and the Oro Loma School. The road network, including Herndon Ave and Shields Ave, follows a rigid section-line pattern typical of California's developed valley floor. Industrial activity is represented by a Gravel Pit near the foothills, while the presence of markers like Gate Mile 95 and Mile 100 along the aqueduct and Pipeline corridors trace the critical infrastructure of the mid-20th century.
