About this map

White Lake dominates the northern expanse of this 1932 coastal survey, revealing the intricate marshland geography of south Louisiana before significant modern modification. The landscape is defined by its transition from open water to the complex drainage of the Floating Turf Bayou, which meanders south from Bear Lake through a saturated environment. To the south, the elevated ridge of Pecan Island emerges from the marsh, providing a stark contrast to the surrounding lowlands.

Mapping of this area reveals a world of remote coastal features, including the aptly named No Mans Land and Long Island. Compiled by the U.S. Geological Survey using aerial photographs from the Army Air Corps, the map captures the state of the Cameron and Vermilion Parish border during a period when these wetlands remained largely accessible only by water, documenting the natural hydrology of the Chenier Plain.
