1967 Map of Calliham

About this map

The Frio River and Nueces River converge in this South Texas landscape, defining a region where river-bottom ranching meets the industrial footprint of the mid-century energy boom. The map highlights the McMullen Co Live Oak Co line, which cuts through a terrain marked by the Ezzel Ranch Oil Field and the Frio River Gas Field. This 1967 survey reveals an era of transition, where established rural communities like Calliham and Simmons are interconnected by a growing network of pipelines and specialized infrastructure such as the Launch Field and a remote Landing Strip. Local landmarks like a Cem near the Nueces and several Gravel Pits suggest a landscape of both deep family roots and active resource extraction. The presence of a Gaging Sta and numerous named drainages like Opossum Creek and White Creek underscores the importance of water management in this arid cattle and oil country.
