Trilha das Cataratas, Iguaçu Falls (Cataratas do Iguaçu), Paraná, Brazil. door ER's Eyes - Our planet is so beautiful.

Upon seeing Iguaçu, the former first lady of the United States, Eleanor Roosevelt, would have exclaimed: - Poor Niagara! The Iguaçu River rises in the Serra do Mar, close to the city of Curitiba, covering the entire state of Paraná through 1,320 km towards the west until it meets the Paraná River on the border with Argentina, Paraguay and Brazil. The waterfalls, whose number varies from 150 to 270, according to the dry and rainy seasons, fall in a width of approximately 2,700 meters, reaching a quantity of 6,500 m3 / s during the flood season. The system consists of 275 waterfalls along 2.7 km of the Iguaçu River. Some of the individual falls are up to 82 meters high, although most are about 64 meters. The Devil's Throat (in Spanish: Garganta del Diablo), a U-shaped drop, is 82 meters high, 150 meters wide and 700 meters long, is the most impressive of all the falls and marks the border between the Argentina and Brazil. Two thirds of the falls are in Argentine territory. About 900 meters of the 2.7 km long, there is no water flowing over it. The edge of the basalt cover recedes about 3 mm per year. The water from the lower Iguaçu accumulates in a canyon that drains into the Paraná River, a short distance from the Itaipu Hydroelectric Plant. The junction between water marks the border between Brazil, Argentina and Paraguay. There are points in the cities of Foz do Iguaçu, in Brazil, Puerto Iguazú, in Argentina, and Ciudad del Este, in Paraguay, which have access to the Iguaçu River, where the borders of the three countries can be seen, a popular tourist attraction for visitors of the three cities.
