This is a spectacular waterfall where the borders of Brazil, Argentina, and Paraguay meet. This picture is taken from Brazil looking at the Argentinian falls. It has three times the water volume of Niagara Falls but spread over a much larger area. There is no effective way of capturing it all in one photograph, at least not from the ground, so I am posting one vignette that I hope captures the feel of the falls.
