The Río de la Plata is the estuary formed by the confluence of the Uruguay River and the Paraná River on the border between Argentina and Uruguay. It is a funnel-shaped indentation on the southeastern coastline of South America, about 290 kilometres long. This nearly cloud-free 300 m image of 7 October 2013 nicely shows the confluence of the two mentioned rivers into the estuary. The sedimentation in the estuary is also visible by the brownish colors.
