2023 Map of San Luis Pass

About this map

Animas Mountains and the Whitewater Mountains define the high elevations of this arid landscape in Hidalgo County. This modern survey illustrates a network of essential water management features critical to ranching and survival in the high desert, such as Big Geronimo Tank, Little Geronimo Tank, and Asten Tank. The presence of Deer Creek Wells central to the map suggests a focal point for activity or livestock management amidst the complex system of ephemeral drainages like Eicks Draw and Lynch Draw. To the south, the San Luis Mountains rise near San Luis Pass, a geographic notch between the ranges. These named landmarks and numerous stock tanks, including Smuggler Tank and Divide Tank, reveal how the landscape is partitioned and utilized for water resources in a region dominated by canyons and dry creek beds.
