1956 Map of Ortigalita Peak

USGS Topo · Published 1966

About this map

Ortigalita Peak dominates the central landscape of this western San Joaquin Valley quadrangle, where the steep terrain of the Panoche de San Juan meets the burgeoning agricultural developments of the valley floor. The map captures a critical era of water management and land use, showing the heavy infrastructure of the Delta-Mendota Canal, the Main Canal, and the Outside Canal as they skirt the foothills. These water systems transformed the arid plains around Hamburg Farms and the Charleston School district into a productive agricultural zone.
