Mouth of Rio de la Plata, Argentina – March 6th, 2009
The Río de la Plata, on the southeastern coastline of South America, is the widest estuary in the world.
It is created by the convergence of the Uruguay River and the Paraná River (visible in detail in the close-up).
The Uruguay River can be seen flowing horizontally, full of dark brown sediments, whereas the Paraná flows vertically and is tan in color.
In the full image, the cities of Buenos Aires, Argentina (center), and Montevideo, Uruguay (right) are visible on the banks of the estuary.
The part of the estuary near Buenos Aires is completely full of tan sediments.
