About this map

The coastal marshlands of Vermilion Parish are defined here by a series of distinct natural elevations and engineered waterways. Mulberry Island stands as a notable landmark among the low-lying wetlands, while a sequence of east-west elevations including Front Ridge, Beef Ridge, and Sand Ridge provides clues to the historical geomorphology of the Louisiana coastline. These ridges often served as the only reliable terrestrial corridors for local inhabitants and livestock in an environment dominated by water.

Industrial and navigational infrastructure is centered on the Freshwater Bayou Canal, which cuts a straight path through the marsh toward the Gulf of America. This corridor, supplemented by the Dewitt Canal and the Freshwater Bayou Channel, illustrates the vital role of water management and maritime access in this region. The presence of LA Hwy 3147 (also labeled State Rte 3147) shows how modern transit follows these narrow, raised landforms like Bill Ridge to navigate the coastal interior.
