2023 Map of Mount Riley

About this map

Mount Riley and Cox Peak dominate this arid landscape in southern Doña Ana County, rising between the West Potrillo Mountains and the East Potrillo Mountains. The terrain is defined by its water-management features, including remote livestock watering points like Davids Tank, Rattlesnake Tank, and Gap Tank. These catchments are critical landmarks in a region largely devoid of permanent surface water. The map traces a network of county roads, such as Co RD a012 and A 05 Co RD, which navigate the wide basins between volcanic peaks. This survey captures the enduring character of the New Mexico ranching and desert frontier, illustrating how geographical features like Chalk Tank and Mesquite Tank serve as vital anchor points for navigation and land use in the Chihuahuan Desert.
