I've read before that the Red Sea crossing was connected with the eruption of Thera. Things that make you go hmmmmm...
Most date the Exodus to about 1450BC. I date it to the time of the Thera eruption which was in 1628BC +-.
The date of the Exodus hasn't been settled. Most scholars date it to the 13th century BC, but many have proposed dates in the 14th or 15th century BC. Most scholars with a high view of the Bible have advocated the 15th century based on textual evidence.
