1979 Map of Presidio East

About this map

Fort Leaton State Historic Site anchors the riverbank of the Rio Grande Rio Bravo in this late 1970s study of the Texas-Chihuahua borderlands. The border town of Presidio is shown as a central transport node, where the Atchison Topeka and Santa Fe railroad crosses a landscape of irrigated fields and desert arroyos. The map details the transition from the irrigated valley floor to the desert uplands, including family and community sites such as Puliques and Campo Santo Estrada. Beyond the valley, the terrain rises into the Black Hills and the Cerros Las Cuchillas. The prominence of local Gaging Stations and pumping infrastructure reflects the vital importance of water management in this arid region, where Cibolo Creek and Alamito Creek drain toward the international boundary.
