Picture of a part of the Iguazy Falls in Brazil / Argentina. The photo is taken from the Brazilian side, but the falls that you see are in Argentina. This is only a small part of the falls. There are about 270-280 falls along 2.7 km (1.67 miles). You can often see mist rising from the falls, and the indians thought that this was where the clouds were born.
I have also seen the Niagra falls, and the Iguazu falls are much more impressive.
