Kaieteur Falls, -Guyana-

 

At Kaieteur Falls, the Potaro stream cascades 741 feet—four times the length of Niagara Falls—in one drop over the arenaceous rock ridge that separates Guyana's highlands from its low-lying rain forests. The wide light-brown sheet thunders down with such force that it kicks up clouds of mist that drift upward higher than the falls.
