Taller than Niagara Falls, twice as wide with 275 cascades spread in a horseshoe shape over nearly two miles of the Iguazu River, Iguazú Falls are the result of a volcanic eruption which left yet another large crack in the earth.

Iguazú Falls lie on the Argentina - Brazil border and are a UNESCO World Natural Heritage Site. The falls are part of a singular practically virgin jungle ecosystem protected by Argentine and Brazilian national parks on either side of the cascades.

Iguazu, Un Viaje Indescriptible is an account by guest author Clarence Fisk, in Spanish, in which he names some of the individual falls, gives us a bit of history as well as a visit to Itaipú Dam and the Parque de las Aves.	Photo from ArtToday

The red speck below the falls is a boat which takes visitors close to the falls. The amount of water coming down the falls depends on the season. In winter, when rains swell the river upstream, the water is higher and muddier.	Photo from ArtToday

Unfortunately, the 1350 sq km reservoir, at 220 m deep, drowned the falls at Sete Quedas, a more impressive set of falls than Iguazú. The dam is open to tours and visitors may view a documentary film about the dam's construction.
