2012 Map of Post Canyon

About this map

The Pecos River carves a winding path through this corner of Val Verde County, defining the drainage patterns of an arid landscape marked by deep incisions and high plateaus. The topography is dominated by large drainage features such as Post Canyon, Brown Canyon, and Live Oak Canyon, which draw toward the river from the surrounding high ground. Human infrastructure is sparse in this portion of West Texas, concentrated primarily along the elevated stretches of Divide Rd in the north and the Tres Ninos Ranch Airport near the river's southern loops. The map captures the specialized ranching and aviation footprint required to manage these expansive landholdings, where road networks follow the natural crests of the divides between the many unnamed draws and larger canyons.
