Earth's Natural Wonders

Extreme Wonders (1x1)

:

Visit extreme locales — from the highest mountain to the greatest canyon — and learn how these places test their inhabitants to the limit. On Mount Everest, a Sherpa has to rope a route across the notorious Khumbu Icefall in time for the hundreds of foreign mountaineers who will arrive for climbing season. In the Grand Canyon, conservationists desperately try to ensure the survival of one of America’s few surviving condor chicks. And, on the slopes of Mount Kilimanjaro in Tanzania, farmers fight pitched battles with elephants in the dead of night.
