About this map

Big Bend National Park reveals its dramatic volcanic and desert topography in this early 1970s survey. The landscape is dominated by the high elevations of the Chisos Mountains and the prominent volcanic plug of Cerro Castellan near the southwestern edge. Human history in this arid environment is evidenced by the Tule Spring Ruins and a network of primitive routes like the Chimneys Trail, which connects geological landmarks such as The Chimneys to more accessible points.

Hydrological features are critical in this terrain, including the Burro Mesa Pouroff and scattered water sources like Wasp Spring and Mule Ear Spring. The map documents the primitive infrastructure of the era, with numerous pack trails winding through the deep relief of Tuff Canyon and toward the striking Mule Ear Peaks. Strategic viewing locations like the Sotol Vista Overlook and Mule Ears Overlook are already established landmarks for visitors navigating the park’s desert floor and mountain passes.
