Great Rift Valley

The Great Rift Valley is mainly in Africa. This is not one simple valley, but a group of related geological structures in East Africa with extensions that reach as far as Syria and Yemen. The Red Sea is geologically a continuation of this system.

Mankind seems to have evolved largely in this valley; see paleontology and man's early migrations. Among the important sites are:
 * Danakil Depression in Ethiopia, with stone tools dating back three million years
 * Olduvai Gorge in Tanzania, with fossils and tools over two million years old

There are many lakes along various branches of the valley. Among them:
 * Lake Tanganyika
 * Lake Victoria, Africa's largest lake and world's second largest by surface area
 * Lake Malawi

Part of the valley is in Kenya and Wikivoyage has articles for the Kenyan regions Southern Rift Valley and Northern Rift Valley. Together they are a, "Kenya Lake System in the Great Rift Valley".
