2017 Map of Tres Hermanos SW

About this map

The southern reaches of the Jarilla Mountains dominate the southeastern corner of this Otero County landscape, providing a stark topographical contrast to the expansive, relatively flat basin floor that covers most of the quadrangle. These foothills are accessed via Co Rd A011, which skirts the mountain base. Further north and west, the terrain is characterized by subtle drainage patterns and isolated water features like North Tank, highlighting the arid nature of this region. Much of the infrastructure shown reflects the military and administrative management of the area, specifically with corridors such as Wsmr S Rt 259 and Wsmr S Rt 252 crossing the desert floor. This 2017 survey delineates the Township and Range boundaries across the T19S, T20S, and T21S sections, documenting the modern survey grid in a territory defined by high-desert land management.
