Synopsis: Atlas 4D explores East Africa's Great Rift Valley. Stretching through thirty five hundred miles of East Africa, from Ethiopia to Mozambique, the Great Rift forms the world's largest system of geological faults. The Rift Valley is so vast it can be seen from space. From its beginnings 35 million years ago, the Great Rift Valley transformed the landscape. And this geological upheaval made some of the iconic East African wildlife what it is today. Atlas 4D travels through time to reveal surprising connections.
