About this map

Lakeshore and Ansley sit at the edge of a complex marshland where the Mississippi coast meets the Louisiana border. This coastal environment is defined by an intricate network of tidal channels including Bayou Caddy, Three Oaks Bayou, and Shrimp Bayou. Near the settlement of Ansley, the Bayou Caddy Cem provides a point of interest for local genealogy, while the grid of roads such as Gulf Ave and Lakeshore Dr show the residential footprint established along the sound.

The southern portion of the map transitions into the open waters of Lake Borgne and the Mississippi Sound, separated by the Intracoastal Waterway boundary. Distinctive landforms like Half Moon Island, Grassy Island, and Point Clear Island dot the shallow waters, illustrating the shifting geography of Saint Joe Pass. These marshy islands and points, including Lighthouse Point and Saint Joseph Point, highlight the navigational significance of this reach for maritime traffic moving through the Grand Island Channel.
