Actually, the highest waterfall in the world is: El Salto Angel or Kerekupai-merú. It is located in the southeast of Venezuela, with about 978 m of height, of which 807 m are uninterrupted falls, which makes it the highest waterfall that even the Niagara.
It was shown to the world in 1935 by American aviator and adventurer James C. Angel, from whom it gets its name.
The river that originates the Angel Falls is called Churún, which is a tributary of the Carrao River, which in turn is the Caroní River. This jump takes its name from the surname of its discoverer, James (Jimmy) Angel, American aviator, who first saw it in 1937 when it flew over this area. The indigenous name of this waterfall is that of Churún Merú.
The cataract is born in the upper part of a plateau (or "tepuy", as they are called to these geological formations) called Auyan Tepuy. These tepuys, together with other geological formations are called "chasms" (which are deep and huge craters, with almost vertical walls), also present in this area, are very old formations, which gives the entire Guayanés Massif an interest geological and biological. It is estimated that within these chasms and at the top of the tepuis there are genera of plants and animals (mainly invertebrates) never seen by man, and even less classified.
