The river flowing from the right is the Iguazu, about two miles below the falls.
The river it flows into is the Paraná River. This is the 2nd longest river in
South America and eventually is called the Rio de la Plata and empties into the sea
at Buenos Aires.

I am shooting on the 3rd floor of our hotel in Argentina. The country across the
Iguazu River is Brazil and the country on the top left is Paraguay!
