2023 Map of Malpais Hill

About this map

United States Of America Estados Unidos Mexicanos defines the southern boundary of this arid landscape in Luna County, marking the transition between New Mexico and Mexico. The terrain is characterized by volcanic and alluvial formations, most notably the southern reaches of the Tres Hermanas Mountains including the prominent Black Top. Water management in this high desert environment is evidenced by features such as Hoppy Tank and Line Ranch Tank, which are critical for the cattle ranching that persists in the region. The map also traces a series of ephemeral drainage paths like Cox Draw, Hermanas Draw, and Simpson Draw. Modern infrastructure is limited to rural thoroughfares like Carzalia Loop and Co Rd C004, providing access across the volcanic slopes of Malpais Hill.
