This appendix is a summary of Olduvai Gorge research.
It is not complete. It may have mistakes too as it has no proof.
Olduvai Gorge is a narrow valley, late Pleistocene through Holocene in age, incised into the southeastern margin of the Serengeti Plains of northern Tanzania, westward of major faults and volcanoes of the Eastern (Gregory) Rift Valley. It was an enclosed saline lake basin, Olduwai Palaeolake (n.a.: southeast-east from Olduvai Gorge there are the calderas of Lemagurut, Sadiman, Ngorongore and Olmoti volcanos).
The Olduvai sedimentary basin was formed at ~2.0 Ma. When formed, the basin was an estimated 3500 km2 in area and roughly circular, ~50 km wide and shallow (100 m) (Ashley and Hay, 2002) [G.M. Ashley et al., 2014, DOI: 10.1016/j.quaint.2013.08.052].
The gorge contains two main branches, the Main Gorge and Side Gorge, which meet in the central ‘Junction’ area about 7 km from where the river disgorges at Olbalbal [L.J. McHenry, 2012, DOI: 10.1016/j.jhevol.2011.04.010].
