Nature: Victoria Falls / Drakensberg: Barrier of Spears

Victoria Falls - Flowing from its source 1,000 miles to the north, the Zambezi River reaches the edge of one world and plummets 350 feet into another. Victoria Falls, spanning the border between Zambia and Zimbabwe, is over a mile wide. No other waterfall in the world can match her scale, which is why many consider her one of the "seven natural wonders of the world." The Zambezi is known as the "River of Life" across southern Africa, but life there is not always easy. Academy Award-winner F. Murray Abraham narrates. Rating: TV-G.

Bonus Program - Drakensberg: Barrier of Spears - Rising sharply from the South African landscape, cliffs like spines of a dragon form the majestic Drakensberg Mountains. Born of Jurassic molten lava, they span more than 600 miles and tower more than 10,00 feet. Despite the impossible terrain and unpredictable weather, Drakensberg is home to a fascinating array of animals. But one animal's perseverance makes it the ultimate survivor: the eland, the largest member of the antelope family. Nature tracks their epic climb in Drakensberg: Barrier of Spears. In order to overcome the ever-changing endurance test cast by nature, these tenacious mountaineers undertake an annual migration toward the summit in search of greener pastures. Academy Award-winner F. Murray Abraham narrates. Rating: TV-G.
