1974 Map of Dilley NE

USGS Topo · Published 1977

About this map

The Frio River dominates this South Texas landscape, carving a meandering path through a region defined by its waterway network and industrial extraction. Topographic data from 1973 reveals a terrain shaped by the confluence of Lockhart Creek, Mule Creek, and Martin Branch. The presence of a Gravel Pit and larger Gravel Pits along the riverbanks suggests a local economy tied to the land's geological resources. Spanning the county line between Frio County and La Salle County, the map documents a sparse, rural environment where an Indefinite Boundary reflects the complexities of surveying this brush-country territory. This record captures the area's transition between agricultural uses and light industrial mining during the mid-1970s.
