Mammoth Journey , Walking with Beasts, BBC Documentary Series, Episode 6

30, 000 years ago, Late Pleistocene (Belgium) Filming location: Yukon The sixth episode takes place during the last Ice Age of the late Pleistocene. It starts in the peak of the summer. The North Sea has become a grassy plain because the ice at the polar caps has caused the sea levels to drop significantly. Grazing on the plain are herds of woolly mammoths, saiga antelopes, and bison. A clan of CroMagnon is also there spending the summer. The central focus of the episode is the migration of the herd of mammoths as they travel 400 kilometres from the North Sea to the Swiss Alps for the winter and then back again in the spring.
