Nancy Anne Ranch serves as the focal point for this Presidio County landscape, where ranching operations are defined by essential water sources like North Tank and Durazno Tank. The terrain is characterized by the prominent Sierra Vieja range and the deep incisions of Howard Canyon, which dictate the paths of primitive access routes such as Chilicote Ranch Rd and Old Brite Rd. The drainage network, including Wild Horse Draw and Ryan Draw, illustrates the arid hydrology of the Trans-Pecos region, where seasonal water flow is funneled through the high desert towards Wild Horse Cr. This 2019 survey documents the enduring layout of family-named ranchlands and the sparse infrastructure required to navigate the high-elevation flats and rocky draws of West Texas.
