About this map

Timbalier Island and the surrounding barrier landscape of the Louisiana coast are captured here during a period of significant industrial expansion. The development of the Caillou Island Oil Field is clearly visible, marked by an intricate network of Oil Wells, pilings, and dolphins used for maritime navigation and extraction infrastructure. This maritime environment is defined by the interaction between the open Gulf of Mexico and the interior Terrebonne Bay.

The map reveals a chain of islands including Casse-tete Island, Brush Island, and Caillou Island, separated by deep-water channels like Caillou Pass and Little Pass Timbalier. While largely devoid of permanent residential settlements, the presence of a Radio Tower and Oil Tanks on the barrier islands underscores the region's mid-century role as a vital hub for the offshore energy industry and coastal monitoring.
