2010 Map of Nancy Anne Ranch

About this map

Sierra Vieja anchors the southwestern corner of this Presidio County landscape, where the terrain is defined by a network of seasonal watercourses and remote ranching outposts. The map reveals the infrastructure of high-desert livestock operations in the early 21st century, centered on sites like Nancy Anne Ranch and Old Chilicote Ranch. Water management is critical in this arid environment, evidenced by the presence of North Tank and Durazno Tank, which collect runoff from the surrounding highlands. Drainage patterns are dominated by deep incisions such as Howard Canyon and a series of ephemeral channels including Walnut Draw, Red Mill Draw, and Wild Horse Creek. A single primary route, Old Brite Rd, provides access to these isolated properties, illustrating the persistent isolation and specialized land use of the Trans-Pecos region.
