2019 Map of Dog Canyon

About this map

Chalk Mountains and the dramatic incision of Dog Canyon define this arid Brewster County landscape. The map details a transition from the elevated peaks in the north to the lower drainage basins where Terlingua Cr flows through the southwestern corner. Human infrastructure is Sparse, primarily consisting of the long north-south corridor of Route 118 and specialized access routes such as Cowboy Mining Co Rd, reflecting the region's history of mineral exploration and ranching. Water management in this high-desert environment is represented by scattered features like Dewees Tank, while ephemeral drainage patterns are mapped through named watercourses such as Hale Draw. The presence of Black Hill in the southeast provides a distinct topographical anchor for those studying the geological and survey markers of the Big Bend region.
