About this map

Chandeleur Sound dominates this coastal landscape, where the shifting edges of Saint Bernard Parish meet the Gulf. The area is defined by fragmented landmasses and intricate waterways, notably Mitchell Island and Martin Island, which stand as significant markers among the surrounding wetlands. Navigation through this aqueous environment is dictated by natural corridors such as Elephant Point Pass and Keelboat Pass, linking larger bodies like Cranetown Bay with smaller, sheltered features such as Conkey Cove and Fox Bay.

The presence of Turtle Pen Isle and Live Oak Bayou suggests a topography shaped by both alluvial processes and tidal influence. This modern survey illustrates the complex, non-contiguous nature of the Louisiana shoreline, where numerous small bays like Drum Bay and Live Oak Bay create a jagged interface between sea and marsh. The map serves as a contemporary record of these fragile coastal landforms and their specific nomenclature within the parish.
