About this map

Jacumba sits at the heart of this high-desert landscape, captured just before the mid-century as a vital international border point. The survey emphasizes the complex infrastructure required for transit through the Jacumba Mountains, notably the winding path of the San Diego and Arizona Eastern railway. This line navigates the dramatic elevation changes of Carrizo Gorge, supported by operations at Dos Cabezas Siding, Dubber Spur, and Titus Siding.

Resource extraction and seasonal water sources define the hinterland, with sites like the Asbestos Mine, Mica Gem Mine, and Bluebird Mine scattered across the arid terrain. The map details the transition from the high peaks of Mt Tule down to the Anza Desert State Park and the Imperial County line. Notable landmarks for travelers and locals alike include Boulder Park and the mysterious Smugglers Cave near the Mexican border.
