1953 Map of Cat Island Pass

USGS Topo · Published 1959

About this map

Caillou Island Oil Field dominates the northeastern corner of this coastal survey, where the Louisiana shoreline meets the expansive Terrebonne Bay. The landscape is defined by its low-lying marshes and the precarious shifting of barrier islands such as Timbalier Island and Wine Island. The interplay of industry and navigation is evident in the placement of an Oil Well and the critical Light and Marker No 1 aiding vessels through the deep waters of Cat Island Pass. At this time in the 1950s, the entire region is recorded as being less than three feet above sea level, emphasizing the fragile geography of the Louisiana delta. The map records the hydrography of the Gulf of Mexico at a moment when offshore resource extraction was establishing its footprint in these southern waters.
