Iguazu Falls, Iguazu Falls, Iguassu Falls or Iguaçu Falls (Portuguese: Cataratas do Iguaçu; Spanish: Cataratas del Iguazu; Guarani: Chororo Yguasu are waterfalls of the Iguazu River on the border of the Argentina province of Misiones and the Brazilian state of Parana. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba. The river flows through Brazil for most of its course, although most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Argentina and Brazil. The name "Iguazu" comes from the Guarani or Tupi words "y", meaning "water", and "uasu , meaning "big". Legend has it that a god planned to marry a beautiful woman named Naipi, who fled with her mortal lover Taroba . In rage, the god sliced the river, creating the waterfalls and condemning the lovers to an eternal fall. The first European to "find" the falls was the Spanish conquistador Alvar Nunez Cabeza de Vaca in 1541.  Source
