About this map

Jordan Gap and Puerto Potrillo serve as the primary passes through the high, flat-topped tablelands of West Texas in this 1917 survey. The landscape is defined by the sharp transition between the massive Whirlwind Mesa and Antelope Mesa and the broad, lower elevations of Paradise Valley and Green Valley. This terrain dictated the early transit routes, including the road leading To Marfa in the northwest and the small settlement of Paradise near the center of the sheet.

Water sources like Alamito Creek and Terlingua Creek are critical features in this arid environment, often acting as the only landmarks between prominent peaks such as Mc Cormick Mtn, San Jacinto Mtn, and Cerro Boludo. The Boundary Line between Presidio and Brewster counties bisects the quadrangle, illustrating how political divisions were laid across the natural topography of the Big Bend region.
