Upon seeing Iguazu Falls, First Lady Eleanor Roosevelt is reputed to have said, "poor Niagara." Having seen them both, that's not hard to imagine. By volume of water, Iguazu Falls is second in the world to Niagara, but much more beautiful in my estimation. This picture captures just a small section of the falls which are two miles in length. The falls form the boundary of Argentina and Brazil, with Paraguay across the river from Argentina just downstream.
