1953 Map of Calumet Island

About this map

East Timbalier Island and its surrounding coastal waters define this survey of the Louisiana shoreline. This environment is characterized by the tension between wildlife conservation and industrial expansion during the mid-20th century, evidenced by the East Timbalier Island Reservation boundary overlapping with active resource extraction. The map documents the extensive infrastructure of the Timbalier Bay Oil Field, where numerous oil tanks and Wells are connected by a network of submerged pipelines. To the north, the more secluded Calumet Island and Casse-Tete Island sit within the waters of Timbalier Bay. Notable navigational and operational markers like a Daybeacon, Light, and even a Flame are recorded, alongside a small Bunk structure on the barrier island, providing a detailed view of the offshore economy and geography prior to modern coastal erosion changes.
