2019 Map of Sierra Parda

About this map

Sierra Parda and the western reaches of the Chinati Mountains dominate this Presidio County landscape, where deep drainages and isolated springs define the remote terrain. The northern territory is bisected by Pinto Canyon Rd, which skirts the base of Cerro de la Cruz and crosses the upper Pinto Canyon. Water sources are critical landmarks in this arid environment, represented by the Indian Spring and the high-elevation seeps at Ojo Acebuche and Ojo Alamito. A complex network of arroyos, including Arroyo Escondido and Arroyo Cienega, illustrates how seasonal runoff has carved the earth over millennia, feeding into major topographical features like the San Antonio Canyon at the southern edge of the survey area. This data, compiled from recent aerial imagery and elevation models, provides an exact record of natural landmarks and primitive transit corridors in the Big Bend region.
