The Gulf of Mexico dominates this coastal landscape in the southern reaches of Louisiana. This maritime environment is defined by open water and tidal influences near the boundary of Plaquemines Parish. While contemporary topographic maps of this region emphasize the vast expanse of the sea, the sheet serves as a primary reference for documenting the shifting maritime boundaries and the proximity of the parish line to the open gulf waters in the mid-2010s.
