1993 Map of Presidio

About this map

The Rio Grande snakes through the center of this borderlands study, defining the international boundary between Texas and Mexico. On the northern bank, the settlement of Presidio serves as a primary hub, mirrored by Ojinaga to the south. The arid landscape is dominated by the massive Chinati Mountains and Cienega Mountains, where the local mining history is clearly etched into the terrain. Industrial remnants include the Chinati Mine, San Antonio Mine, and Sullivan Mine, concentrated near the settlement of Shafter. Transport routes like Highway 67 and Highway 170 connect these isolated outposts, while the Presidio Lely International Airport provides a modern link to the broader region. The map captures a complex network of ephemeral drainages such as Cibolo Creek, Alamito Creek, and Wilson Arroyo, illustrating how water shaped the cattle ranching and mineral extraction patterns of this high desert environment.
