2018 Map of Freemason Island OE W

About this map

Chandeleur Sound dominates this coastal landscape in Saint Bernard Parish, Louisiana. This maritime environment is characterized by its isolation and the shifting geography of the gulf coast. A small landmass, Old Harbor Island, is the sole named terrestrial feature within the survey area, providing a critical reference point for researchers of Louisiana's barrier islands and coastal evolution. The map depicts a moment in time when this remote segment of the sound remained largely undisturbed by significant human development, focusing instead on the hydrography of these outlying waters.
