Iguazu Falls — South America's Mightiest Waterfall

Iguazu Falls are
waterfalls of the Iguazu River located on the border of the Brazilian
State of Paraná and the Argentine Province of Misiones. The falls divide
the river into the upper and lower Iguazu. The Iguazu River starts at
the city of Curitiba and runs for the most part of the course in Brazil
and at the end at the border of Brazil and Argentina. More images after

Their name comes from the Guarani or Tupi words y (water) and
ûasú [waˈsu] (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 Bosellz at the end of the nineteenth century, and
one of the Argentine falls is named after him. Iguazu Falls was
short-listed as a candidate to be one of the New7Wonders of Nature by
the New Seven Wonders of the World Foundation. As of February 2009 it
was ranking fifth in Group F, the category for lake, rivers, and
waterfalls. Via Link
