1960 Map of Tecate

About this map

Tecate sits directly on the international border in this early 1960s study of the San Diego County backcountry. The map details a landscape defined by hydraulic engineering and historical transit, featuring the San Diego City Conduit with its complex system of siphons, flumes, and tunnels snaking through the hills. This infrastructure highlights the critical role of water management in the region's development. Settlement is concentrated at Barrett Junction and Dulzura Summit, while the presence of the Old Stage Route and Tecate Road provides a view into the transportation corridors that linked these border communities. To the south, a Customhouse marks the entry point into Mexico. Notable peaks like Tecate Peak and Potrero Peak overlook the valleys where Cottonwood Creek and Potrero Creek flow, punctuated by local landmarks such as the Barrett Sch and various mountain springs.
