Where Did They Cross The Sea?

There does remain however some uncertainty as to the precise route of the Exodus, and just where the parting of the sea occurred. Those who insist that it was the "Red Sea" as we know it today, may be overlooking the fact that in ancient times the Red Sea may have extended much farther north than it does now (the Dead Sea in Israel is another example of changed natural boundaries over thousands of years). It is very possible that the Bitter Lakes and Lake Timsah today (it was through that natural series of waters that the modern Suez Canal was constructed) are merely remnants of a more northerly Red Sea that now ends with the Gulf of Suez.

The map above illustrates 4 possible places where the parting of the sea occurred. Numbers 1 to 3, the Gulf of Suez, the Bitter Lakes, and Lake Timsah are all possibilities, while number 4, the so-called "northern route" through Lake Bardawil, would seem to be much less probable.
