2025 Map of Curlew Islands

About this map

Chandeleur Islands and the Curlew Islands emerge as delicate geological markers in this coastal survey, situated where the Chandeleur Sound meets the expansive Gulf of America. This specific maritime environment highlights the shifting nature of Louisiana's outer barrier island chains, which serve as the primary line of defense for the mainland against the open sea. The sparse labeling reflects a landscape dominated by water and low-lying coastal landforms, providing a clear reference for the positioning of these islands before ongoing coastal erosion and tidal changes further alter their footprint. The separation between the sound and the gulf illustrates the complex hydrography of the region, where shallow estuarine waters transition into the deeper currents of the gulf.
