2019 Map of Four Mills

About this map

Dry Devils River defines the western corridor of this West Texas landscape, where the ephemeral waterway carves through the high plateau at the border of Val Verde and Edwards counties. This 2019 survey documents a sparsely populated ranching region centered on the Four Mills locality. The terrain is dominated by a complex network of drainage systems, including the prominent Buffalo Draw and County Line Draw, which illustrate the natural watershed patterns of the Edwards Plateau. Man-made interventions in this arid environment are largely limited to vital water infrastructure like the Rock Barn Tank and the path of Buffalo Rd. The map provides a precise record of how livestock ranching and natural topography interact in this transition zone, where the only significant development follows the course of the dry riverbed and the county line.
