[Young Werther]

There was a shuttle mission that used an earth penetrating radar to scan the globe. I remember radar pictures of Egypt which disclosed geological features which were hidden by the sand. The change in the course of the Nile, eons ago, was readily visible. Might a search of these images be fruitful?

Might a search of these images be fruitful?

Surprising we don't hear more of these. Might have to do with the present Antiquities Admin of Egypt.
