2012 Map of Las Islas Ranch

About this map

Las Islas Ranch serves as the central landmark for this arid section of South Texas, where the landscape is defined by a sparse but critical network of water infrastructure. The territory is marked by numerous family-named and descriptive water sources, including the Brazil Windmill, Borrego Windmill, and San Antonio Windmill, reflecting the ranching heritage of the Rio Grande Valley. These points of extraction were essential for sustaining livestock in a region where surface water is scarce. Transportation is limited to a few arterial routes such as FM-2686 and local tracks like Rancho San Blas Rd, which connect the isolated ranching operations. The distribution of sites like La Purisma Windmill and Cinca de Mayo Windmill across the grid indicates the deliberate planning required to manage vast tracts of rangeland in Starr County.
