About this map

Louisville and Nashville Railroad tracks cut across the marshy northern edge of this coastal landscape, connecting the small settlement of Toulme to the wider Gulf Coast trade network. The map reveals a complex aquatic environment where the Mississippi Sound meets the fragmented wetlands of St Bernard and the northern bayous. Maritime safety is a clear priority in these shallow waters, evidenced by the Merrill Shell Bank Light and a St. Joseph Island Light guarding the entrance to Grand Island Pass.

The intricate network of waterways, including Bayou Caddy, Trois Chenes Bayou, and Bayou Bodreau, suggests a landscape defined by water transport and seasonal changes. These tidal channels weave through named points and islands such as Lower Point Clear, Grassy Island, and the larger Grand Island, providing a detailed look at the coastal morphology before twentieth-century modifications altered many of these low-lying features.
