Iguazu Falls are waterfalls of the Iguazu River on the
border of the Argentine province of Misiones and the Brazilian state of
ParanĂ¡. The falls divide the river into the upper and lower Iguazu.
Taller than Niagara Falls and twice as wide, Iguazu
Falls are the result of a volcanic eruption which left a large crack in
the earth. During the rainy season of November – March, the rate of flow
of water going over the falls may reach 450,000 cubic feet (12,750
cubic m) per second.
