1969 Map of Big Canyon Ranch

About this map

Downie Draw carves a deep path across this landscape, serving as the primary drainage feature in a region defined by isolation and high desert ranching. At the end of the 1960s, the terrain was dominated by large private holdings such as the Big Canyon Ranch and Hagelslein Ranch, where life centered on the sparse water sources and the occasional Corral. An Indefinite Boundary and the line for Pecos Co Terrell Co cut across the northwest, reflecting the complexities of surveying this remote Texas borderland. The presence of smaller named points like Russell and Dudley Ranch suggests a network of family-operated livestock operations that relied on the seasonal flow of the draws and the scattered wells drilled into the limestone substrate. This map offers a technical look at the land use and topographic character of the Trans-Pecos region before modern infrastructure further altered the historic ranching boundaries.
