2019 Map of Sue Peaks

About this map

Big Bend National Park defines the southern reach of this Brewster County landscape, where the dramatic elevation changes of the Sierra del Carmen and Sierra del Caballo Muerto meet. This terrain is characterized by a complex network of drainage systems and high ridges, notably including the namesake Sue Peaks and the elongated Sierra Larga. Low-lying areas such as Margaret Basin and Ernst Valley are tucked between these massive limestone formations, providing a stark contrast to the surrounding heights of Hubert Ridge. The presence of Telephone Canyon and its northern branch suggests historical routes through the mountains, while more modern access is indicated by Stillwell Crossing Rd and Ranch Rd 2627 near Heath Canyon. This survey captures the topographical intricacies of the Trans-Pecos, from the seasonal flows of Heath Cr to the prominent landmarks used by generations of travelers.
