2019 Map of San Esteban Lake SW

About this map

Frenchman Hills and the Black Hills define this high-desert region of Presidio County, where ephemeral watercourses have carved a complex network of drainage basins. The landscape is dominated by the winding paths of Perdiz Creek and Cienega Creek, which reveal the erosional patterns of the Trans-Pecos. A primary artery, Highway 67, bisects the terrain, providing the only major transit corridor through these elevated rangelands. The proximity of several smaller tributaries, such as Matonoso Cr and Dunman Cr, illustrates the hydrological dependency of the area’s remote ranching history. This 2019 survey documents the modern topographic state of these western Texas uplands, emphasizing the stark relationship between the high peaks and the dry creek beds that define the local geography.
