THE AFRICAN WATERFALLS.

Lake Mak-gadik-gadi is an ancient Lake in the Kala-Hari Dessert in Bots-Wana, South Africa. It once covered as much as 80,000 km2 and was 30 m deep.
It was born approximately 3 million years ago, when strong Easterly Winds formed the elongated Dunes running from East to West across the Middle of the Kala-Hari Dessert. During wetter times, these Dunes channeled the flow of the 3 great Rivers of the area, the Okavango, Zambezi, and Kuando, once all emptied into the Lake.
Then 2 millions years ago, the Fault known as the Kala-Hari-Zimbabwe Axis formed, running from the Zimbabwe Capital Harare through its 2nd largest City Bulawayo and ends in the Eastern Side of the Kala-Hari, creating an enormous Basin and forced these Rivers to flow into and fill up the Basin. Lake Mak-gadik-gadi was thus born.
As the millennia passed, the Lake was filled beyond capacity and began to overflow. Then, about 20,000 years ago, as a result, it began to drain NorthWards and then EastWards. This caused the Middle and Lower Zambezi Rivers to connect, resulting in the formation of Victoria Falls (Mosi-oa-Tunya, the real name in the language of the locals) at the border of Zambia and Zimbabwe. It is believed that the first European that arrived to the scene was a Scottish missionary and explorer named David LivingStone on 1855. One of the 2 Land Masses in the middle of the River, immediately upstream from the Falls is now known LivingStone Island. The explorer also named the Falls in honor to Queen Victoria, Victoria Falls, but the use of the ancient name, Mosi-oa-Tunya -"The Smoke that Thunders"- continues in common usage to the inhabitants of the area.
In 2013, the government of Zimbabwe declared its intention to officially rename the Falls "Mosi-oa-Tunya," citing continuity with other re-names such Harare (from Salisbury), and Zimbabwe (from Rhodesia).
While it is neither the highest nor the widest in the World, i the Fall is classified as the Largest, based on its Width of 1,708 m (5,604 ft) and Hight of 108 m (354 ft), resulting in the World's Largest Sheet of Falling Water. Mosi-oa-Tunya (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 the African Falls is rivaled only by Argentina and Brazil's Iguazu Falls.
