2012 Map of Timbalier Island

About this map

Timbalier Island and the surrounding barrier landforms of the Louisiana coast are captured here in a period of significant environmental transition. This portion of the Gulf of Mexico is defined by a sparse but industrial landscape, where the shifting sands of Caillou Island and Brush Island exist alongside active extraction at the Caillou Island Oil Field. The map illustrates the tenuous nature of these low-lying coastal features, including the Pelican Islands, which serve as vital buffers for the mainland. The presence of the oil field among these eroding landmasses highlights the intersection of the region's petroleum economy and its fragile maritime geography during the early 21st century.
