1956 Map of San Pedro Ranch

About this map

The San Pedro Ranch landscape in Kenedy County is defined by an intricate network of Shifting Sand Dunes, where elevations rise and fall across the brushland of the South Texas plains. Mapping work conducted by the Geological Survey reveals a remote ranching environment where survival depended entirely on scattered water sources. The map records a high density of named wells and windmills, such as the San Antonio Windmill and Santa Cruz Well, which anchored the local cattle operations. These features, connected by a web of unimproved dirt roads and property fences, illustrate the spatial organization of early-to-mid 20th-century ranching. The presence of San Pedro and family-named sites like La Piedra Well provides specific points of interest for genealogists and local historians tracing the heritage of this sparsely populated coastal prairie region.
