Port Arthur and its surrounding coastal industrial corridor define the western edge of this 1970s survey, showing a landscape shaped by the Neches River and the Sabine River. The region’s reliance on maritime trade and petroleum is evident in the sprawling oil and gas fields and the complex of jetties and lights, including the Southwest Pass Lighthouse, that guide traffic through the gulf inlets. Moving eastward, the industrial character yields to the massive wetlands of the Sabine National Wildlife Refuge and Lacassine National Wildlife Refuge, where a network of canals like Stark's Canal and the Intracoastal Waterway thread through the marsh.
