2022 Map of Post Canyon

About this map

The Pecos River carves a deep, sinuous path through this landscape, serving as the historical boundary between Crockett and Terrell counties. This 2022 survey illustrates the extremely isolated and vertical character of the Trans-Pecos region, where complex drainage systems like Post Canyon and Tanislado Canyon feed into the river valley. The terrain is marked by a network of named draws and ridges, including Live Oak Canyon and Brown Canyon, which underscore the geographic challenges of the territory. Human presence is sparse, centered primarily on large-scale ranching operations as evidenced by the Tres Ninos Ranch Airport in the south and the winding path of Co Rd 413 to the east. This map offers a precise view of the modern county lines at the intersection of Crockett, Terrell, and Val Verde counties.
