About this map

The Government Wells Oil Field and surrounding energy landscapes dominate this South Texas terrain during the early 1970s. The region is defined by a dense network of extraction infrastructure, where extensive pipelines and access roads connect various producing zones including the Lundell Oil Field and the Sarnosa Oil Field. Amidst these industrial operations, the map shows the scattered ranching and logistical footprint of the era, marked by the Daval Ranch and a remote Landing Strip.

Natural features like Sarnosa Hill and Cedro Hill provide the vertical relief in an otherwise subtle landscape drained by ephemeral watercourses such as Colmena Creek and Animas Creek North. Strategic water management for livestock and industry is evident through features like the Colmena Tank, while the presence of a Radio Tower and Rest Area indicates the modernization of this rural Duval County corridor.
