Iguazu Falls

Iguazu Falls, Iguassu Falls, or Iguaçu Falls (Portuguese: Cataratas do Iguaçu ; Spanish: Cataratas del Iguazú) 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 waterfall system consists of 275 falls along 2.7 kilometers of the Iguazu River. Position is at latitude (DMS): 25° 40' 60 S, longitude (DMS): 54° 25' 60 W . Some of the individual falls are up to 82 meters in height, though the majority are about 64 metres. The Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese), a U-shaped, 82-meter-high, 150-meter-wide and 700-meter-long cataract, is the most impressive of all, and marks the border between Argentina and Brazil. Two thirds of the falls are within Argentine territory. About 900 meters of the 2.7-kilometer 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 in the Paraná River at Argentina, shortly downstream from the Itaipu dam.
