2023 Map of Sentinel Butte

About this map

Alamo Hueco sits at the heart of this high-desert landscape in the southwestern corner of New Mexico, where the plains meet the rising slopes of the Alamo Hueco Mountains. The terrain is defined by dramatic geological features, including the prominent landmark of Sentinel Butte and the deep incisions of Wood Canyon and Black Canyon. These canyons and the surrounding drainages, such as Bear Creek, Bull Creek, and Willow Creek, illustrate the complex hydrology of Hidalgo County. Access to this remote region is primary facilitated by Alamo Hueco Rd, which traverses the basin. This survey documents the area's essential geographic character, from its sharp topographic relief to the sparse but critical network of seasonal watercourses that shape the southern New Mexico borderlands.
