About this map

Jordan Gap serves as the focal point for this 1917 survey of the High Desert region in the Trans-Pecos, documenting a landscape defined by dramatic topography and sparse water sources. The map reveals a complex network of canyons and plateaus, including Antelope Mesa and Whirlwind Mesa, alongside the prominent Paradise Valley. Geodetic control and topography were managed by engineers like R.W. Berry and O.H. Nelson under the direction of the War Department.

Ephemeral watercourses such as Alamito Creek and Terlingua Creek dictate the local geography, providing vital drainage through this arid corridor. The survey delineates the boundary line between Presidio and Brewster counties, passing through landmarks like McKinney Mtn. Notable peaks such as Church Mtn and Housetop Mtn offer fixed points for navigation in a region where the only improved road shown is the route To Marfa.
