Loma Alta serves as a central landmark in this South Texas landscape, where the petroleum industry and cattle ranching shape the terrain. Extensive energy operations are evident through the Hagist Ranch Oil Field, the Seven Sisters Oil Field, and the Eagle Hill Oil Field, supported by the Hagist Ranch Gas Plant. These industrial sites are interspersed among historical family holdings such as Hagist Ranch and Foster Ranch. Drainage is defined by the winding paths of San Jose Creek and Drummond Creek, which flow through the brush country. Prominent elevations like Loma Pinta and the presence of Walker Lake with its Walker Lake Dam illustrate the local reliance on water management in an area characterized by scattered rural settlements like Seven Sisters.
