1979 Map of Sinton East

About this map

The coastal plains of San Patricio County are defined by a complex intersection of energy extraction and transportation networks in the late 1970s. The landscape is heavily marked by the Portilla Oil and Gas Field and the Plymouth Oil and Gas Field, with numerous drill holes and pumping stations scattered across the terrain. This industrial footprint is anchored by the eastern edge of Sinton, where the High Sch and Radio Towers (KIKN) serve as local landmarks near the junction of the Southern Pacific and Missouri Pacific railroads. Natural drainage systems like the Aransas River and Chiltipin Creek wind through the region, creating a stark contrast between the riparian corridors and the geometric patterns of the surrounding oil fields and agricultural tracts. The map also captures smaller locales like Moody and specialized infrastructure such as a Heliport and several wind-driven water sources including the Lagarto Windmill.
