1969 Map of Sabinal NE

About this map

Seco Valley defines the landscape of this Medina County quadrangle, where the drainages of Seco Creek and Parkers Creek cut through the South Texas brush country. The map captures a transition toward specialized land use during the late 1960s, most notably with the sprawling Automotive Test Facility located in the western sector. This industrial footprint, complete with its own Landing Field, stands in contrast to the traditional ranching landscape marked by numerous Wells and drainage systems like Cedar Creek and Rocky Creek. The presence of a Gravel Pit along the eastern bluffs suggests local resource extraction, while the intermittent nature of Comanche Creek and Live Oak Cr reflects the arid character of the region. This survey serves as a detailed record of how mid-century engineering and large-scale testing grounds began to reshape these rural Texas creek valleys.
