2020 Map of San Luis Pass

About this map

Deer Creek Wells serves as a focal point in this high-desert region of Hidalgo County, where water management is the primary signature of human activity. The landscape is defined by an extensive system of catchment features including Big Geronimo Tank, Little Geronimo Tank, and Malpais Tank, highlighting the vital importance of water security for ranching in the arid Southwest. This topography is framed by the Animas Mountains to the west and the Whitewater Mountains to the east, with San Luis Pass providing a natural corridor through the San Luis Mountains. Numerous ephemeral drainages like Eicks Draw, Aiken Draw, and Lynch Draw carve through the basin, illustrating the complex natural irrigation patterns that dictate the placement of local landmarks and infrastructure in this borderland territory.
