Kaieteur Falls combination of height and water volume, and Kaieteur is among the most powerful waterfalls in the world with an average flow rate of 663 cubic metres per second (23,400 cubic feet per second). Kaieteur Falls is about four times higher than Niagara Falls, on the border between Canada and the United States, and about twice the height of Victoria Falls, on the border of Zambia and Zimbabwe in Africa. It is a single drop waterfall. Upriver from the falls, the Potaro Plateau stretches out to the distant escarpment of the Pakaraima Mountains. The Potaro River empties into the Essequibo River
Victoria Falls of kilometres in all directions. The falls are formed as the full width of the river plummets in a single vertical drop into a transverse chasm wide, carved by its waters along a fracture zone in the basalt plateau. The depth of the chasm, called the First Gorge, varies from at its western end to in the centre. The only outlet to the First Gorge is a wide gap about two-thirds of the way across the width of the falls from the western end. The whole volume of the river pours into the Victoria Falls gorges from this narrow cleft.
