Brazil Waterfall

The name Iguaçu comes from the Guarani or Tupi words y (water) and guasú (big). Legend has it that a god planned to marry a beautiful aborigine named Naipí, who fled with her mortal lover Tarobá in a canoe. In rage, the god sliced the river creating the waterfalls, condemning the lovers to an eternal fall. The first European to find the falls was the Spanish Conquistador Álvar Núñez Cabeza de Vaca in 1541, after whom one of the falls in the Argentine side is named. The falls were rediscovered by Boselli at the end of the nineteenth century, and one of the Argentinian falls is named after him.

The waterfall system consists of 275 falls along 2.7 kilometres (1.67 miles) of the Iguazu River. Some of the individual falls are up to 82 metres (269 feet) in height, though the majority are about 64 metres (210 feet). The Garganta del Diablo or Devil's Throat (Garganta do Diabo in Portuguese), a U-shaped 150-metre-wide and 700-metre-long (490 by 2300 feet) cliff, is the most impressive of all, and marks the border between Argentina and Brazil. Most of the falls are within Argentine territory. About 900 metres of the 2.7-kilometre length does not have water flowing over it. The edge of the basalt cap recedes only 3 mm per year.

The water of the lower Iguazu collects in a canyon that drains into the Rio Parana. and this is located in Argentina.
