The Gulf of Mexico dominates this coastal survey, where the terrestrial footprint is reduced to small, low-lying landforms within Plaquemines Parish. At the center of the sheet, Bird Island stands as a discrete feature in an area otherwise characterized by open water and shifting coastal inlets. The presence of Taylor Pass indicates the navigational channels that have historically defined the movement of vessels through the Mississippi River Delta region. This specific survey provides a record of the shoreline and landmass configuration during the mid-2010s, reflecting a landscape in constant flux. The section markers such as t19s r18e provide a cadastral reference for the maritime and marshland boundaries in this portion of southern Louisiana.
