About this map

The Charamusca Oil Field dominates this South Texas landscape along the Webb and Duval county line during the mid-1970s. This industrial corridor is defined by an extensive network of pipelines, access roads, and numerous oil wells, reflecting the intensive energy extraction characteristic of the Brush Country. A central refinery and associated pumping station serve as local hubs for production, while a substation and radio tower mark the technical infrastructure required to maintain operations across the wide-open terrain. Away from the drilling sites, the natural drainage patterns of Colmena Creek, Black Creek, and Charamusca Creek cut through the landscape, providing a sharp contrast to the geometric lines of the resource extraction industry. The map captures a specific moment in the evolution of these Texas oil lands, documenting everything from scattered drill holes to active gravel pits.
