About this map

The fragile barrier islands of Terrebonne Parish, Louisiana, are documented here just before the middle of the 2010s. This coastal environment is defined by the shifting interface between the Gulf of Mexico and protected interior waters like Trinity Bay. The geography is characterized by narrow strips of land and significant industrial maritime infrastructure, notably the Block 8 Seaplane Base located at the eastern edge of the island chain. This facility reflects the ongoing importance of air and sea logistics in the region's offshore economy.

Waterways and coastal landforms dictate the landscape, from the western reaches of Bayou l'Ourse to the artificial cut of the California Canal. Natural landmarks such as Bodwin Point and Point Mast provide reference points in an area where the coastline is subject to constant change. The presence of Trinity Bayou further illustrates the complex network of tidal channels that carve through these southern Louisiana reaches.
