The Iguaza waterfalls in northern Argentina are higher than Niagara Falls and four times as wide.

It's one of the new natural wonders of the world, according to the same company that organized last year's popular if controversial New Seven Wonders of the World campaign.

The Iguaza waterfalls in northern Argentina are higher than Niagara Falls and four times as wide.

The waterfalls were formed by a volcanic eruption. The resulting crack in the earth separates the falls into an upper and a lower section, dividing their home between Brazil and Argentina.

Its crescent-shaped cliff spans almost three kilometers. The 270 separate cascades attract thousands of visitors every day from all over the world.

The Iguaza was established as a Natural World Heritage Site by UNESCO in 1984.
