Greyish tan sediments fill the Gironde Estuary and line part of the west coast of France. The sediments in the estuary come from the Dordogne and Garonne Rivers.
Visible at the base of the estuary is the city of Bordeaux (bottom center). Another city, Nantes, can also be observed as a grey area in the upper left quadrant. Other cities and towns appear as grey dots across the otherwise green landscape.
