1971 Map of Cerro Castellan

About this map

Cerro Castellan rises as a prominent landmark within the expanse of Big Bend National Park in this 1971 survey. The landscape is defined by its significant topographic relief, from the volcanic spires of the Mule Ear Peaks to the broad plateau of Burro Mesa. For historians and researchers, the map identifies specific points of human activity and passage, including ruins near Tule Spring and a primitive transportation network consisting of the Chimneys Trail and various other pack trails. Water sources were critical in this arid environment, marked here by Mule Ear Spring, Burro Spring, and Wasp Spring. Dramatic geological features like Tuff Canyon and The Chimneys are clearly delineated alongside the Chisos Mountains foothills, showing the park's interior before the increase in modern visitor infrastructure.
