1983 Map of Cerro Redondo

About this map

The Rio Grande forms a prominent international boundary in this borderlands region of Presidio County, marking the transition between Texas and Chihuahua. Infrastructure in the early 1980s was defined by the Atchison Topeka and Santa Fe railroad, which cuts through a landscape shaped by intermittent water sources and ranching outposts. Isolated sites like Gavino Tank, Botilla Camp, and a small Cem suggest the sparse, enduring settlement patterns of the Big Bend country. The terrain rises to distinct peaks such as Cerro Redondo and the Black Hills, while drainage is managed through a complex network of seasonal channels including Terneros Creek and Alamito Creek. Numerous windmills and springs, such as Calera Spring and Palo Amarillo Spring, highlight the essential reliance on groundwater for livestock and survival in this arid environment.
