2025 Map of Grand Gosier Islands

USGS Topo · Published 2025

About this map

The Chandeleur Islands chain marks a critical maritime boundary where the sheltered waters of Breton Sound meet the open Gulf of America. This coastal survey highlights a landscape defined by isolation and shifting sands, focused on the Grand Gosier Islands and the solitary Gosier Island to the southwest. The absence of contour data on this sheet reflects the extreme low-lying nature of these barrier features, which serve as the first line of defense for the Louisiana mainland against the gulf.
