1969 Map of Loma Alta

About this map

The boundary between McMullen Co and Duval Co divides a landscape defined by mid-century energy production and ranching operations. In the late 1960s, the terrain was dominated by the Hagist Ranch Oil Field and the Seven Sisters Oil Field, featuring a dense network of pipelines, oil wells, and gravel pits. The infrastructure of the Hagist Ranch Gas Plant stands as a significant industrial landmark amidst the arid South Texas brush country.
