Where on Earth? - December 2013

Clues for December 2013:
1.  Famed Scottish missionary and explorer David Livingstone is said to have been the first European to see these magnificent falls, which span 1,700 meters across, while on an expedition in 1855. The falls, and the river of which they are a part, form an international border.
2.  In the rainy season, up to 500 million liters per minute plunge over the falls, which reach 100 meters high. The torrent of water then drains through a zigzagging series of gorges cut into joints in thick, layered basalts thought to have erupted about 180 million years ago.
3. The spray from the falls rises hundreds of meters into the air, can be seen from tens of kilometers away, and is the origin of the indigenous name for the falls, which translates to "the smoke that thunders." The mist also sustains patches of lush, species-rich forest amid the otherwise arid savanna.
Name the waterfall and the countries it separates.

Answer: In the rainy season, up to 500 million liters of water from the Zambezi River plunge each minute over the 100-metertall Victoria Falls, also called Mosi-oa-Tunya ("the smoke that thunders"), before flowing away through gorges cut into thick layers of basalt. The river and falls form part of the international border between Zambia and Zimbabwe. Photo is by Amy Vukovich Dale.
