1982 Map of Dos Hermanos Peaks

About this map

Dos Hermanos Peaks anchors this landscape in Webb County, rising above a dry-land drainage system characterized by intermittent waterways and cattle tanks. This 1982 provisional survey illustrates the ranching infrastructure of South Texas, where names like Lazarine Tank, Maquey Tank, and Corralitos Tank point to the critical importance of managed water sources in an arid environment. The terrain is defined by the winding paths of Espada Creek and Blanca Creek, which cut through the Tierra region. The mapping of small features such as Muerta Tank and Tasajillo Tank provides a detailed look at land use and specific landmark names used by local ranchers and land managers in the late twentieth century, long before modern digital satellite imagery replaced these hand-checked manuscript drawings.
