About this map

Twin Peaks and the Chalk Mountains dominate this high-desert landscape in Brewster County, where the northern reaches of Big Bend National Park meet private ranchlands. The topography is defined by intricate drainage systems including West Corazones Draw, East Corazones Draw, and the winding Nine Point Draw. These seasonal watercourses are punctuated by essential desert water sources such as Buttrill Springs, Alamo Spring, and Goat Spring, which have historically sustained both wildlife and human activity in this arid environment.

Transportation through this isolated section of the Trans-Pecos relies on routes like Marathon Rd and the Terlingua Ranch Rd, which navigate the elevation changes near the Rosillos Mountains. The map reveals a network of smaller ranch and residential tracks, including Sombrero Peak Ranch Rd and Casa Manana Ln, illustrating the modern human footprint among the ancient geological formations of Jack Eden Mesa and Trough Canyon.
