Victoria Falls from Zimbabwe
Victoria Falls, or Mosi-oa-Tunya ( Smoke that Thunders), is a waterfalls in southern Africa on the Zambezi River at the border of Zambia and Zimbabwe.
David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view Victoria Falls on 16 November 1855 from what is now known as Livingstone Island, one of two land masses in the middle of the river, immediately upstream from the falls on the Zambian side. Livingstone named his discovery in honor of Queen Victoria, but the indigenous name, Mosi-oa-Tunya—"the smoke that thunders"—continues in common usage as well.
It is a UNESCO World Heritage site.
While it is neither the highest nor the widest waterfall in the world, it is classified as the largest, based on its width of 1,708 metres (5,604 ft) and height of 108 metres (354 ft), resulting in the world's largest sheet of falling water. Victoria Falls is roughly twice the height of North America's Niagara Falls and well over twice the width of its Horseshoe Falls . In height and width Victoria Falls is rivalled only by Argentina and Brazil's Iguazu Falls.
The falls are formed as the full width of the river plummets in a single vertical drop into a transverse chasm 1708 metres (5604 ft) wide, carved by its waters along a fracture zone in the basalt plateau.
There are two islands on the crest of the falls that are large enough to divide the curtain of water even at full flood: Boaruka Island (or Cataract Island) near the western bank, and Livingstone Island near the middle—the point from which Livingstone first viewed the falls. At less than full flood, additional islets divide the curtain of water into separate parallel streams. The main streams are named, in order from Zimbabwe (west) to Zambia (east): Devil's Cataract (called Leaping Water by some), Main Falls, Rainbow Falls (the highest) and the Eastern Cataract.
The Zambezi river, upstream from the falls, experiences a rainy season from late November to early April, and a dry season the rest of the year. The river's annual flood season is February to May with a peak in April. The spray from the falls typically rises to a height of over 400 metres (1,300 ft), and sometimes even twice as high, and is visible from up to 48 km (30 mi) away. At full moon, a "moonbow" ( Lunar Rainbow) can be seen in the spray instead of the usual daylight rainbow. During the flood season, however, it is impossible to see the foot of the falls and most of its face, and the walks along the cliff opposite it are in a constant shower and shrouded in mist. Close to the edge of the cliff, spray shoots upward like inverted rain, especially at Zambia's Knife-Edge Bridge.
David Livingstone wrote of the falls, "No one can imagine the beauty of the view from anything witnessed in England. It had never been seen before by European eyes; but scenes so lovely must have been gazed upon by angels in their flight."
