2020 Map of Rock Tank Draw

About this map

Rock Tank and its namesake Rock Tank Draw define this arid landscape in Hidalgo County, where water management is central to the terrain's history. The map illustrates a network of drainage features including Railroad Wash, Cottonwood Canyon, and Thompson Draw, which carve through the high desert between the Summit Hills to the south and the Black Hills in the northeast. This 2020 survey documents the modern ranching and energy infrastructure that underpins the region, from the Double M Ranch Rd to the prominent El Paso Gas Line crossing the southeastern corner. The arrangement of labeled features like Hughs Canyon and Dagger Draw reveals the complex topography of the Animas Valley area, where seasonal water flow and livestock requirements have historically dictated the location of vital points like the Rock Tank.
