[2] David Neev conducted stratigraphic analysis in 1967 to provide further evidence from a sequence of sediments left by the lake.
[3] Archaeological evidence supports the geological with no Epipaleolithic sites on the western side of the Beisan Basin below 100 metres below sea level.
During the Neolithic, the lake receded to approximately 200 metres below sea level due to erosion and formation of the Jordan River and an arid phase that peaked around 8500 BC.
Later in the Neolithic the climate became dryer and the lake further retreated to around 220 metres below sea level between 6500 and 5500 BC as the flow through the Jordan Valley decreased.
The Jordan River gradually deepened sufficiently for all remnants of the lake to have disappeared by the time of the Middle Bronze Age.
