About this map

Pass A Loutre and its branching waterways define the deltaic landscape of Plaquemines Parish in this 1954 compilation, based on aerial photography from the mid-1930s. The map illustrates a complex network of active and inactive distributaries where the Mississippi River meets the Gulf of Mexico. Historical maritime infrastructure is evidenced by the Pass A Loutre L. H. (Discontinued), positioned near Lighthouse Bayou, marking a site once vital for navigation through these shifting silts.

Family and local names appear across the marshlands, including Tommy Dantz Bayou, Willie Bayou, and Meyers Bayou, suggesting the areas historical use for trapping, fishing, or small-scale navigation. Unique geological features such as the North Mud Lumps and Thomasin Lumps are recorded along the edge of the Middle Ground, capturing the volatile nature of the delta as land is simultaneously built and reclaimed by the sea.
