2018 Map of Breton Islands SE

About this map

Japan Island and the adjacent waters of the Japan Outside Pond occupy the southwestern corner of this coastal survey in Plaquemines Parish. Most of the quadrangle is defined by the open expanse of the Gulf of Mexico, illustrating the fragile nature of the Louisiana shoreline where land meets the sea. The map, produced by the U.S. Geological Survey, records a minimal number of named landforms, reflecting a remote maritime environment subject to the shifting tides and currents of the gulf. This document serves as a precise record of the coastal geography as it existed in the late twenty-tens, capturing a landscape where only a few distinct marshes and ponds remain identified by name.
