Iguazu Falls, Brazil and Argentina
Iguazu Falls, Iguazú Falls, Iguassu Falls, or Iguaçu Falls (Portuguese: Cataratas do Iguaçu; Spanish: Cataratas del Iguazú; Guarani: Chororo Yguasu) are waterfalls of the Iguazu River on the border of the Argentina province of Misiones and the Brazilian state of Paraná. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba. For most of its course, the river flows through Brazil, however, 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. Iguazu Falls are located where the Iguazu River tumbles over the edge of the Paraná Plateau, 23 kilometres (14 mi) upriver from the Iguazu's confluence with the Paraná River. Numerous islands along the 2.7-kilometre-long (1.7 mi) edge divide the falls into many separate waterfalls and cataracts, varying between 60 to 82 metres (197 to 269 ft) high. The number of these smaller waterfalls fluctuates from 150 to 300, depending on the water level. Approximately half of the river's flow falls into a long and narrow chasm called the Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese) - see image above! The Devil's Throat is U-shaped, 82 metres high, 150 m wide, and 700 m long. Placenames have been given also to many other smaller falls, such as San Martín Falls, Bossetti Falls, and many others.
