Abstract
The Middle Awash Valley, Afar, Ethiopia, contains a sedimentary sequence that is > 1 km thick, spans much of the Neogene, and contains vertebrate fossils throughout. Newly defined formations described here are older and younger than the hominid-bearing Hadar Formation. The Awash deposystem reflects deposition in an evolving triple junction.
