Whose river produces the largest tropical waterfall system by flow?
Quick Answer
The Iguazú River feeds Iguazú Falls. The falls span the border between Brazil and Argentina and include hundreds of separate cataracts.
The Full Story
Iguazú Falls are formed by the Iguazú River, which runs through subtropical forest in South America. The waterfall system lies on the Brazil–Argentina border and consists of a long series of cascades and drops rather than a single plunge. One of the most famous sections is the Devil’s Throat, a horseshoe-shaped chasm with tremendous spray and noise. The falls are part of a UNESCO World Heritage site and a major ecological area. Their power comes from the river’s broad flow over resistant basalt rock.
