2020 Map of Malpais Hill

About this map

The high desert terrain of southern Luna County defines this landscape, where the international boundary with Mexico forms the southern limit of the survey. The topography is dominated by the volcanic forms of Malpais Hill and the southern reaches of the Tres Hermanas Mountains, including the prominent Black Top. This arid environment is marked by intermittent drainage patterns such as Hermanas Draw, Simpson Draw, and Cox Draw, which channel seasonal water across the plains. Human presence in this borderland is traced through cattle ranching infrastructure and desert roads. Ranching relies on isolated water sources like Hoppy Tank and Line Ranch Tank, while the local transportation network is comprised of Carzalia Loop and several county roads that navigate the open range between the mountains and the border.
