1893 Map of Chandeleur

About this map

Chandeleur Sound dominates the eastern landscape of this coastal survey, where the shifting sands of the Louisiana barrier islands are captured during a late-19th-century mapping project. Compiled from the work of the U. S. Coast and Geodetic Survey, the map documents the fragile geography of the outer marsh and island systems. Significant landforms like Mitchell Key and Martin Island appear alongside smaller features such as Barrel Key, illustrating the coastal morphology before decades of erosion and tropical storms reshaped the archipelago. Navigational channels like Elephant Point Pass and Keelboat Pass provide essential markers for the maritime history of St. Bernard, while Pt. Comfort and Live Oak Bayou denote specific landmarks in this low-lying environment where the entire area is noted as being less than five feet above sea level.
