2020 Map of Freemason Island OE W

About this map

Chandeleur Sound dominates this coastal landscape in Saint Bernard Parish, representing a dynamic environment where the Gulf of Mexico meets the outer fringes of the Mississippi River delta. This survey captures a nearly purely maritime environment, focusing on the open waters and submerged features of the sound. The presence of Old Harbor Island in the southeastern corner provides a critical landmark for understanding the shifting barrier island systems of Louisiana. Because this is a modern topographic study, it reflects the contemporary state of these sensitive island chains, which are vital for coastal protection. Genealogists and local historians tracking family maritime history or commercial fishing patterns in the Louisiana marshlands will find this map essential for orienting historical records against the modern shoreline.
