2020 Map of Breton Islands SE

About this map

Japan Island and the neighboring Japan Outside Pond occupy a small, isolated corner of this maritime landscape in Plaquemines Parish. This coastal area is defined by the vast reach of the Gulf of Mexico, where a thin, dotted line indicates the changing boundary between the open sea and the fragile marshlands of the delta. This 2020 record serves as a precise point-in-time observation of these features, capturing the tenuous relationship between small named islands and the surrounding saltwater environment during a period of significant coastal evolution.
