1994 Map of Cat Island Pass

About this map

Timbalier Island anchors this coastal survey, showing a narrow barrier of sand and marsh separating the open Gulf of Mexico from the sheltered waters of Terrebonne Bay and Lake Pelto. In the mid-1990s, the maritime landscape is defined by energy infrastructure, with numerous offshore platforms and tanks dotting the Caillou Island Oil and Gas Field. Navigational aids like a light and Marker No 1 guide vessels through the deep water of Cat Island Pass. The map highlights a dynamic environment where the land is constantly reshaped by the tides, as evidenced by various shoals and the shifting shoreline of the island itself. This record is particularly valuable for documenting the precise footprint of industrial development and the state of Louisiana's fragile barrier islands at the close of the 20th century.
