1964 Map of Lake Theriot

About this map

Lake Theriot and the expansive waters of Lake De Cade dominate this coastal Louisiana landscape, reflecting a region defined by its complex network of natural bayous and industrial waterways. Settled activity is concentrated along the narrow natural levee of Bayou du Large, where the small community of Theriot and the Lower Bayou du Large Sch are situated. The 1960s environment captured here shows an era of intensive resource extraction, indicated by the South Sunrise Oil and Gas Field and several marked Oil Wells. The map also reveals the engineered transformation of the wetlands through features like the Marmande Canal, Minors Canal, and the Falgout Under Construction Canal. Amidst this modern industry, ancient history is preserved at the Indian Mound near the eastern marshes, while named landforms like Congo Island and the Ridge provide topographic variety in the surrounding marshes.
