Here is a concession re the suitability of the Bitter Lakes by Graham Davies who otherwise speaks of the biblical texts as late compilations of ‘traditions’. I will maintain that it is impossible for so much geographical detail to have survived hundreds of years as ‘tradition’ and written up by people who had never been to these regions and still be accurate across the books and match the terrain.
 Another possibility which deserves renewed consideration is that… the Bitter Lakes, where many scholars would locate [the crossing] on the basis of features other than the reference to ‘Yam Suf’, were continuous with the Gulf of Suez and so naturally known by the same name. Subsequently the land rose and the lakes were separated from the Gulf, and then it was more appropriate to refer to the place of the crossing as ha-yam (which could mean ‘the lake’); while the tradition of a crossing of Yam Suf, which was not completely suppressed, led to a new location of the event on the Gulf of Suez. The geological events assumed by this theory can be shown to have occurred by the evidence of rock-formations near Suez and around the Bitter Lakes* but it has never been shown conclusively that the Bitter Lakes were joined to the open sea in the historical period…. But the discoveries that have been made are compatible with a lowering of the shore-level of up to 2 metres in the  historical period, and this seems to be all that the proponents of the northerly extension of the Gulf of Suez envisage.** Moreover, both Glueck and Rothenberg hold that there has been such a change in the shore-level at the north end of the Gulf of Aqaba.***
