About this map

The Alamo River meanders through this agricultural landscape in California's Imperial Valley, following a survey conducted in the mid-1950s. The terrain is defined by an intensive network of irrigation and drainage infrastructure, including the Holtville Main Drain, Moorhead Levee, and numerous alphabetically named laterals such as the Oak Lateral and Oxalis Lateral. This intricate water management system supported small rural communities and educational centers, including Alamorio, Orita, and the Magnolia Union Sch.

Transportation and industry are closely tied to the geography, with the Southern Pacific railroad line running north-south through the settlements of Curlew and Sandia. Local agricultural operations are marked by features like Grain Tanks, a Pumphouse, and several rural schools such as the Rose Mesquite School and Pine Union School, reflecting the era's decentralized community structure before the further consolidation of valley towns.
