2023 Map of Mount Riley SE

About this map

The international border between the United States and Mexico defines the southern edge of this desert landscape, where the Chihuahuan terrain transitions into the federally protected Organ Mountains-Desert Peaks National Monument. In the northeastern corner, the steep contours of the East Potrillo Mountains dominate the horizon, while the surrounding basin is marked by sparse but essential infrastructure for life in the arid borderlands. Water management features like Sand Tank and Border Tank are located alongside remote thoroughfares such as A003 Co Rd and Co Rd A004. The presence of the Riley Black Standpipe Mount suggests the specialized utility and navigation points required for managing and traversing this stretch of Doña Ana County during the early twenty-first century.
