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.

Natural topography is punctuated by prominent rises like Loma Alta, Loma Pinta, and Eagle Hill. Water is a scarce and vital resource, represented by seasonal drainages such as San Jose Creek and Drummond Creek, along with local landmarks like Devils Waterhole. The map captures the quiet intersection of family-owned ranching land and the industrial footprint of the Texas oil boom, providing a clear view of the area's development before modern expansion.
