1959 Map of Jacumba

About this map

The high desert landscape of the In-Ko-Pah Mountains and Jacumba Mountains dominates this mid-century survey of the California-Mexico border. Centered on the settlement of Jacumba, the map captures the community just as modern revisions were documenting its evolving footprint, including the nearby Airport and localized infrastructure like a Trailer Park. The rugged topography is traversed by the San Diego and Arizona Eastern railroad, which navigates the steep grades of Carrizo Gorge with features like Tunnel 15 Spur and Dubber Spur. This area is defined by its critical water sources in an arid environment, from the well-known Bankhead Springs and Dos Cabezas Spring to the curiously named Arsenic Spring. Much of the northern terrain is preserved within the Anza Borrego Desert State Park, where landmarks like Mortero Palms and Piedras Grandes mark the transition from rocky peaks to desert washes.
