I have seen many maps showing where the Jews crossed "Yam Suf" (Usually translated as the Red Sea). Then they show where the Jews traveled, where is Mt. Sinai, where did the Jews encamp, etc.
Where does this information come from? Did we keep a tradition for the past 3000 years where was the splitting of the sea and where in the Sinai desert was the actual Mt. Sinai? Are the locations documented in Rishonim? Did Artscroll or Kol Menachem consult Archeologists?
