2015 Map of New Harbor Islands

About this map

New Harbor Islands fragments are the focal point of this coastal survey, illustrating the ephemeral nature of the Louisiana shoreline. Located within St. Bernard Parish, these landforms sit at the interface of the open Gulf of Mexico and the relatively sheltered Chandeleur Sound. The map captures the specialized geography of the outer marsh and island chain, where the boundary of Louisiana is defined by these shifting maritime features. The absence of roads, structures, or inland terrain highlights the isolation of this environment, which serves as a critical buffer for the mainland delta against the tidal forces of the Gulf.
