1953 Map of Western Isles Dernieres

About this map

Isles Dernieres stretches across this mid-century survey, forming a critical barrier between the open Gulf of Mexico and the calmer waters of Caillou Bay. This coastal landscape in Terrebonne Parish is characterized by shifting sandy points and tidal inlets, most notably Raccoon Point and Coon Point at the western terminus of the island chain. The map provides a look at the maritime geography before decades of coastal erosion further altered these barrier islands.
