2020 Map of Sentinel Butte

About this map

Alamo Hueco serves as a central reference point in this arid landscape of southern Hidalgo County, where the desert floor of the Playas Valley meet the rising elevations of the Alamo Hueco Mountains. This 2020 survey illustrates a region defined by its drainage patterns and vertical topography, centered on the distinctive profile of Sentinel Butte. The terrain is deeply incised by seasonal waterways such as Bear Cr, Bull Cr, and Willow Cr, which flow from the higher reaches of Black Canyon and Wood Canyon. These geographical features dictate the path of the few established thoroughfares, notably Alamo Hueco Rd, which traverses the center of the quadrangle. The map provides a precise view of the Public Land Survey System divisions, documenting the township and range boundaries that organize this remote New Mexico borderland.
