1960 Map of Potrero

About this map

Cleveland National Forest dominates the mountain landscape of southern San Diego County in this early 1960s survey. The map details a rugged borderland defined by the California Baja California line, where the settlement of Tecate sits directly against the international boundary. Water management infrastructure is central to the area's development, featuring the Morena Reservoir and Barrett Lake connected by the Cottonwood Creek drainage and the historic path of the San Diego Flume. Rural life is marked by isolated outposts like Bichenaugh Ranch, Walker Ranch, and the Barrett Sch at Barrett Junction. The terrain is punctuated by high points such as Tecate Peak and Lawson Pk, while the presence of a Marine Memorial near Hauser Canyon provides a localized historical marker within the forest's many valleys.
