David Livingstone be de first European dem record to view de falls on 16 November 1855, from an island now be known as Livingstone Island, one of two land masses insyd de middle of de river, immediately upstream from de falls near de Zambian shore.[2] Livingstone name ein sighting in honour of Queen Victoria, buh de Lozi language name, Mosi-oa-Tunya—"The Smoke That Thunders"—continue in common usage.

Victoria Falls National Park marker

De Upper Zambezi River originally drain south thru present day Botswana to join de Limpopo River.[8][9] A general uplift of de land between Zimbabwe den de Kalahari Desert about 2 million years ago block dis drainage route, den a large paleolake dem know as Lake Makgadikgadi form between de Kalahari den de Batoka Basaltic Plateau of Zimbabwe den Zambia. Na dis lake originally be endorheic wey e get no natural outlet. Under wetter climate conditions about 20,000 years BP, e eventually overflow den begin to drain to de east, wey dey cut de Batoka Gorge thru de basalt.[10][11][12]
