1967 Map of Calliham NW

About this map

The Dragoon Oil And Gas Field defines much of the southern landscape of this McMullen County quadrangle in the late 1960s, reflecting the region's mid-century energy production. Several Pipeline routes and scattered oil wells punctuate the brush country, illustrating the industrial infrastructure that overlays the natural drainage basins. The Frio River winds through the northern portion of the map, fed by tributaries like Salt Branch, while the central and southern terrain is carved by Dragoon Creek and Dragoon Hollow. Evidence of small-scale extraction is visible at various Gravel Pit locations near Landers, a solitary named settlement hub in a region primarily dedicated to ranching and resource recovery. This survey captures a specific moment when traditional Texas land use intersected with an intensifying search for subterranean wealth in the South Texas plains.
