1986 Map of Del Rio

Strategic military and transit history is visible through the positioning of Fort Clark Springs and Brackettville along the central corridor, while the Southern Pacific railroad tracks trace a path through rural settlements like Spofford and Standart. Local landmarks like Alamo Village and the high point of Salmon Peak stand out against a network of drainages including Sycamore Creek, Pinto Creek, and the Nueces River, illustrating the complex water systems of the Edwards Plateau and Rio Grande plain.
