The Guadalupe River and San Marcos River converge in this South Texas landscape, anchoring a region defined by agricultural heritage and the mid-century expansion of the petroleum industry. Numerous named oil fields, including the Egleto Oil Field and Thomaston Oil Field, are scattered across the terrain, indicating the intensive energy extraction that shaped the local economy by the 1980s. The transportation network is dominated by the Southern Pacific Railroad, which links established settlements like Nixon, Smiley, and Westhoff.
