1958 Map of Borrego Mountain SE

About this map

The Lower Borrego Valley floor and the arid Fish Creek Mountains dominate this 1958 survey, conducted as the Anza-Borrego Desert State Park boundaries were established across the Imperial and San Diego county lines. The map reveals the industrial and survival infrastructure of the mid-century desert, most notably a Mining Railroad leading toward a quarry and several dry water sources such as Baileys Well and County Well (Dry) Spring. The settlement of Little Borrego is already noted as a site, while the Old Kane Spring Road provides a primary transit link across the valley. North of the mountains, the Ocotillo Badlands and San Felipe Creek illustrate the stark hydraulic geography of the region, including the seasonal Halfhill Lake and the dramatic gap at Split Mountain.
