2019 Map of Las Islas Ranch

About this map

Las Islas Ranch anchors this portion of Starr County, situated along a network of remote ranching roads that crisscross the arid South Texas landscape. This 2019 survey, produced by the U.S. Geological Survey using imagery from the National Agriculture Imagery Program (NAIP), reveals a territory defined by expansive grazing lands and a sparse but deliberate infrastructure. The map follows the path of Ranch Rd 2686 as it cuts through the terrain, connecting isolated ranch sites. Smaller routes like Alaniz Rd and San Blas Ranch Rd branch off from the main thoroughfares, providing access to private holdings. The terrain is marked by subtle shifts in elevation, meticulously captured by the National Elevation Dataset, showing the dry drainage patterns and land contours that dictate the layout of these vast cattle operations in the borderlands region.
