1956 Map of Port Arthur

About this map

Port Arthur and its surrounding coastal marshlands are depicted here during a period of mid-century industrial and maritime expansion. The map illustrates the complex water systems of the Chenier Plain, where the Intracoastal Waterway links the major basins of Sabine Lake, Calcasieu Lake, and White Lake. The landscape is defined by its ridges or cheniers, such as Grand Cheniere Ridge and Pumpkin Ridge, which provide the only high ground for settlements like Grand Cheniere and Pecan Island.
