Freemason Island stands as a solitary geographic marker within the expansive waters of Chandeleur Sound in this 2015 survey. Located in Saint Bernard Parish, this coastal region is defined by the open reaches of the Gulf of Mexico, where the barrier island landscape is constantly reshaped by maritime forces. The map illustrates the minimal land area typical of this outer reach of the Mississippi River Delta, where few named land features emerge from the surrounding sounds. This document records the precise position of the island at a specific moment in time, providing a reference for researchers tracking coastal change, shoreline migration, and the shifting geography of Louisiana's southeastern coastal fringes.
