The United States-Mexico border defines the lower edge of this Imperial County landscape, where the intensive irrigation of the valley meets the arid expanse of the Yuha Desert. The vast engineering of the All American Canal and Central Main Canal supports the agricultural infrastructure around the town of Heber. To the west, the New River carves a path through the valley, while the Southern Pacific railroad provides the vital link for the region's produce. The map documents the local community structure of the early 1940s, anchored by landmarks like the Mt Signal Union Sch and the Mtn View Cem. To the southeast, the border crossing at Calexico serves as the gateway to Baja California, showing the town's grid at the very edge of the international line.
