1994 Map of Western Isles Dernieres

USGS Topo · Published 1994

About this map

Raccoon Island stands as a prominent remnant of the barrier island chain known as the Isles Dernieres, separating the open Gulf of Mexico from Caillou Bay. This coastal environment in Terrebonne Parish is characterized by shifting sands and strategic maritime passages, including Coupe Colin and the marsh-fringed Grand Pass des Ilettes. The 1990s-era landscape reveals the significant footprint of the offshore energy industry, with the Block 40 Gas Field, Pass des Ilettes Gas Field, and Pass Wilson Oil and Gas Field dotting the waters. At Racoon Point and Coon Point, the delicate intersection of Gulf currents and landforms is meticulously documented. The presence of a stationary Platform and various Shoal markings highlights the navigational hazards and industrial activity central to this stretch of the Louisiana coast during the late twentieth century.
