Kaieteur

Kaieteur Falls is one of the most powerful single-drop waterfalls in the world. It is located on the Potaro River in Kaieteur National Park, central Essequibo Territory, Guyana. It is 226 metres (741 ft) high when measured from its plunge over a sandstone and conglomerate cliff to the first break. It then flows over a series of steep cascades that, when included in the measurements, bring the total height to 251 metres (822 ft). While many falls have greater height or greater flow, few have the 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 meters per second (23,400 cubic feet per second). Kaieteur Falls is about four and a half times the height of 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.
