2. The falls are located on an important river in the area

As the name of the waterfalls implies, the falls are located in the Iguazu River. This is one of the major rivers in the area as it has a total length of 1,320 kilometers (820 miles) and a drainage basin of 62,000 square kilometers (24,000 square miles).

The Iguazu River is also one of the main tributaries of the Paraná River, which with a length of 4,880 kilometers (3,030 miles) is the second-longest river in South America after the Amazon River.

The waterfalls divide the river into the Upper Iguazu River and the Lower Iguazu River. The Lower part is basically a canyon that drains into the Paraná River.

3. The majority of the falls are located in Argentina

The falls have the shape of a reversed “J” and are divided between the two countries Brazil and Argentina. The east bank of the river is located in Brazil and is the smallest part consisting of just 20% of the falls.

This means that the majority of the falls, which consists of 80%, are located within the borders of Argentina. This is remarkable because 95% of the drainage basin of the Iguazu River is located within the borders of Brazil.

4. This is how the waterfalls were created according to a legend

The origin of the name of the river and waterfalls can be traced back to the Guarani language. It’s a combination of the words “y,” which means “water” and “ûasú,” which means “big.”

There’s also a legend as to how the waterfalls were created. Word around the campfire spread that a god was in love with a beautiful girl named Naipí, but instead of answering his love, she ran off with her real lover, a man named Tarobá.

A chase ensued as they jumped into their canoe and sped off. The god was so angry that he sliced the river in half and created the falls, condemning the two lovers to an eternal fall.

5. The falls consist of two enormous steps

While this is hard to judge when you look at the falls from a certain angle, they actually consist of two massive steps. One of these steps is about 35 meters high (115 feet) while the other step is about 40 meters (131 feet) high.

They exist exactly on the location where the Paraná Plateau ends and the Iguazu River tumbles over the edge. This divide is 2,682 meters (8,800 feet) wide.

6. About 1/3 of the edge doesn’t have water flowing over it

The height of the edge of the Paraná Plateau varies between 60 and 82 meters (197 and 269 feet). One of the most remarkable facts about the Iguazu Falls is that not all areas of this edge have water flowing over it to create a single waterfall.

Depending on the flow of the water, the Iguazu Falls actually consist of between 150 and 300 distinct different waterfalls, as opposed to single curtain waterfall as for example Victoria Falls in southern Africa.

7. Half of the water of the river falls into one particular canyon

As the river tumbles over the edge of the Paraná Plateau, about half of the water flows into one particular canyon referred to as the “Devil’s Throat,” locally known as the “Garganta del Diablo” in Spanish and “Garganta do Diabo” in Portuguese.

This amazing canyon is between 80 and 90 meters (260 and 300 feet) wide and has a height of between 70 and 80 meters (230 and 260 feet).

The largest distinct waterfalls of the Iguazu Falls also have names. There’s the San Martín, Adam and Eva, Penoni, and Bergano Falls!
