1985 Map of Santiago Mountains

About this map

The Santiago Mountains dominate this 1980s landscape in Brewster County, forming a prominent spine that divides the drainage basins of Terlingua Creek and Maravillas Creek. The area is characterized by isolated outposts like Butcherknife and Cochran, connected by the sparse corridor of Texas 118. To the south, the boundary of Big Bend National Park and the Black Gap State Wildlife Management Area preserve the transition from high mesas like Kokernot Mesa and Nine Point Mesa to the desert floor. The map captures a period of modern ranching and conservation efforts, where landmarks like Santiago Peak and Agua Fria Mountain serve as essential navigational points. In the southeast, the Sierra del Carmen begins its dramatic rise, while intricate drainages like Chalk Draw and Bone Spring Draw reveal the complex hydraulic patterns of the Big Bend region.
