2013 Map of Ernst Valley

About this map

Rio Grande waters define the eastern edge of this arid landscape, winding past the dramatic elevation of Hubert Ridge and the deep incision of Cow Canyon. The terrain is dominated by the massive Sierra del Caballo Muerto, which overlooks a series of topographical depressions and drainages including Ernst Basin and the central Ernst Valley. Water management in this high-desert environment is evidenced by the presence of the Ernst Tank, a crucial resource in a region otherwise marked by seasonal features like Heath Cr and Arroyo Venado. This survey provides a precise view of the complex landforms and drainage patterns along the international border as they were documented in the early 21st century.
