2018 Map of Eastern Isles Dernieres

About this map

Isles Dernieres, a fragile chain of barrier islands off the coast of Terrebonne Parish, dominate this 2018 coastal survey. These islands separate the open Gulf of Mexico from the intricate network of bays and passes to the north, including Trinity Bay and Terrebonne Bay. The landscape is defined by the constant movement of water through features like Old Camp Pass and Wine Island Pass, which facilitate the exchange between the interior marshlands and the sea. Inland, landmarks such as Bodwin Point and Point Mast rise above the surrounding water, marking the transition from the gulf to the shallower reaches of Bay Blanc and Pass la Poule. This map documents a highly dynamic environment where features like Trinity Bayou and Bodwin Cutoff illustrate the evolving shoreline and the persistent natural forces shaping the Louisiana deltaic coast.
