Iguazu Falls

Iguazú Falls or Iguaçu Falls are waterfalls of the Iguazu River on the border of the Argentine provinceof Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the heart of 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. The name "Iguazú" comes from the Guarani or Tupi words "y" [?], meaning "water," and "ûasú "[wa?su], meaning "big." Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers to an eternal fall. The first European to record the existence of the falls was the Spanish Conquistador Álvar Núñez Cabeza de Vaca in 1541. The staircase character of the falls consists of a two-step waterfall formed by three layers of basalt. The steps are 35 and 40 m in height. The columnar basalt rock sequences are part of the 1000 m thick Serra Geral Formation within the Paleozoic-Mesozoic Paraná Basin. The tops of these sequences are characterized by 8-10 m of highly resistant vesicular basalt and the contact between these layers controls the shape of the falls. Headwater erosion rates are estimated at 1.4-2.1 cm/year. The 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. The Iguazu Falls are arranged in a way that resembles a reversed letter "J." The Argentina-Brazil border runs through the Devil's Throat. On the right bank is the Brazilian territory, which is home to more than 95% of the Iguazu River basin but has just over 20% of the jumps of these falls, and the left side jumps are Argentine, which makes up almost 80% of the falls. Two international airports are close to Iguazú Falls: the Argentine Cataratas del Iguazú International Airport (IGR) and the Brazilian Foz do Iguaçu International Airport (IGU). Bus and taxi services are available from and to the Airport-Falls. Aerolíneas Argentinasand LATAM Argentina[5] have direct flights from Buenos Aires to Iguazu International Airport Krause. Azul, GOL, and LATAM Brasil offer services from main Brazilian cities to Foz do Iguaçu. The Iguazu Falls experience a humid subtropical climate (Cfa, according to the Köppen climate classification) with abundant precipitation and high temperatures year-round.
