One of the greatest waterfalls in the whole world lies on the Zimbezi River, which forms the border between Zambia and Zimbabwe. Some people think it is one of the most beautiful sights in the world. Upstream, the river flowed through a wide valley. You could probably see Victoria Falls from 25 to 40 miles away and see its spray rising 1,000 feet into the air from seven miles away. Long before you even see the waterfalls you can hear the roaring of the water. Victoria Falls was discoverd by David Livingstone in 1855. The falls were named in honor of Queen Victoria. There is no doubt that Victoria Falls is a Wonder of The Natural World.
