1965 Map of Dolores Ranch

About this map

The Rio Grande defines the character of this West Texas borderlands survey, where the international boundary between the United States and Mexico remained fluid due to the river's shifting course. The landscape is marked by a sophisticated water management system essential for ranching in this arid environment, featuring an extensive network of earthen reservoirs such as Anita Tank, Tasita Tank, and Escondido Tank. Near the riverbanks, an aqueduct and a dedicated Pumping Station supported the operations at Dolores Ranch. Evidence of earlier transport and industry is preserved in the Old Railroad Grade and several Mine Dump sites. For genealogists, the map identifies local burial sites including Darwin Cemetery and Dolores Cemetery, providing spatial context for families associated with the ranching and mining history along the border.
