My proposed date of the Exodus is 1491 BC, at the end of Dynasties 6 and 12.
However, I also propose an alternate stratigraphy where the Ice Age ended and the Younger Dryas Impact Event occurred around the time of the Exodus. The Greeks record three floods in the Mediteranean region: Ogyes, Dardanus, and Deucalion. There are actually two floods of Deucalion, the older one being the Genesis Flood. The younger one was around 1450 BC and may represent the Zanclean Flood which overtopped Gibraltar and refilled the Mediteranean.
Therefore I would expect to find Middle and Old Kingdom port cities and settlements under the sea in the Gulf of Suez and in the Delta about 40 miles North of the current shoreline.
