About this map

Dolores Ranch and the small settlement of Islitas anchor this mid-1960s landscape along the winding Rio Grande, where the river serves as the international boundary between the United States and Mexico. The terrain is defined by an extensive network of water management features essential for ranching in Webb County, including Venancio Tank, Escondido Tank, and Anita Tank.

Evidence of historical industry and transit is scattered throughout the quadrangle, from the Old Railroad Grade and its associated Aqueduct to remnants of earlier resource extraction visible at the Mine Dump near Santo Tomas Creek. Genealogists and local historians can locate the Darwin Cemetery in the northwestern sector, while the presence of a Landing Strip and Pumping Station near the riverbank reflects the local infrastructure of the mid-20th century.
