Imagine more than a million litres of water dropping each second from cliffs up to 80 metres, or 262 feet, high. Such an image may seem like an impossibility, but such is the majesty of South America's Iguazu Falls. More expansive than both the Niagara Falls in North America and the Victoria Falls in Africa, The Iguazu Falls is a network of more than 275 falls covering many acres. The falls lie on the border of Brazil and Argentina and both countries have created national parks around the natural marvel. The falls divide the upper and lower sections of the Iguazu River. The river's course runs over a basaltic plateau or volcanic plain. The falls begin where the lava beneath stopped running. Along the ridge there are many hidden reefs and rocks that divide the river into its many channels and allow for the overall waterfall effect. One of the most famous of the water cataracts is the 'Devil's Throat'. iMinds will tell you the story behind the place with its innovative travel series, transporting the armchair traveller or getting you in the mood for discover on route to your destination. iMinds brings targeted knowledge to your eReading device with short information segments to whet your mental appetite and broaden your mind.
