The Rio Grande forms the southern boundary of this South Texas landscape, where the international border is defined by river meanders and historic land tracts. Near the riverbanks, the settlement of Cuevitas and the specialized plots of Santos Banco Number 95 and Cuevitas Banco Number 96 reflect the unique cadastral history of the Rio Grande Valley. Further north, Sullivan City serves as the primary hub, organized around a grid of streets like 1st St and 3rd St, while the surrounding terrain is marked by long, narrow property lines extending toward El Toro Ranch. Transport patterns are defined by the parallel paths of Military Rd and Old Military Rd, which follow the natural curve of the river valley. The arid landscape is dotted with ephemeral water features such as Salado Cr, Cobby Lake, and La Joya Lake, illustrating the hydrological character of the region during this era.
