About this map

The South Texas brush country at the McMullen and Duval County line is defined by a sprawling landscape of energy extraction and ranching as seen in the late 1960s. The Hagist Ranch Oil Field, Seven Sisters Oil Field, and Eagle Hill Oil Field dominate the topography, revealing a complex network of pipelines and service roads linking numerous Oil Wells and the Hagist Ranch Gas Plant. This industrial footprint is overlaid on established grazing lands like the Hagist Ranch and Foster Ranch, illustrating the dual-use nature of the land during the mid-century petroleum boom.
