2016 Map of Sombrero Peak

About this map

Sombrero Peak serves as a central landmark in this high-desert region of Brewster County, where the topography transitions from the dramatic rises of the Rosillos Mountains to the level expanse of Onion Flat. The landscape is defined by its vital water sources, with Onion Spring, Rock House Spring, and Dripping Spring indicating historical points of survival for ranchers and travelers alike. The map captures the northern frontier of Big Bend National Park, illustrating the remote ranching infrastructure through corridors like Sombrero Peak Ranch Rd and Brewster Rd. The network of ephemeral drainages, including Tornillo Cr and East Corazones Draw, dictates the natural movement across this arid terrain, leading toward the prominent Paint Gap Hills and the southern mountain passes.
