Sal del Ray, a natural salt lake, dominates the landscape of this South Texas region, where ranching and energy extraction define the local economy. The area around San Manuel and Linn is characterized by an extensive network of family-named ranches and windmills, reflecting the vital importance of groundwater management in this arid environment. Key sites include the San Felipe Ranch, El Rucio Ranch, and Tres Corrales Ranch, interspersed with infrastructure such as the San Manuel Gas Field and Sal del Rey Gas Field. Local history is anchored at the El Rucio Cemetery, while a system of named routes like Chapa Rd and El Rucio Rd connect the scattered homesteads and windmills that populate the territory north of the Rio Grande Valley.
