2019 Map of Hagler Canyon

About this map

Hagler Canyon and Isinglass Canyon carve through this section of the Trans-Pecos, where Brewster and Terrell counties meet. The landscape is defined by a dense network of deep drainage systems, including Whitely Canyon to the north and the jagged Washboard Canyon to the west. Human presence is sparse, marked primarily by the winding Cochran Rd and Highway 90, which follows the course of Sanderson Canyon in the northeast corner. This 2019 survey by the U.S. Geological Survey illustrates how the physical geography dictates the placement of infrastructure in this arid region, with transportation routes forced to navigate the high plateaus between seasonal watercourses like Sanderson Cr and Cedar Cr. The map provides a precise record of the topography and modern county boundaries in a remote portion of West Texas.
