1969 Map of Hagler Canyon

About this map

Deep drainage networks including Whitely Canyon and Hagler Canyon dominate this landscape on the border of Terrell and Brewster Counties. The 1969 field-checked survey reveals a remote West Texas terrain defined by erosion and seasonal water management, where isolated Water Tanks and a Well represent the vital infrastructure for ranching and transit. The Southern Pacific railroad cuts through the northeastern corner, following the natural contours near Putman Canyon. This transit corridor highlights the historical reliance on natural gaps and canyons to navigate the Trans-Pecos region. Smaller tributaries like Isinglass Canyon and Washboard Canyon feed into larger systems, illustrating the complex topography encountered by surveyors and early travelers in this arid environment.
