<HTML>Hi Claire,
With regard to the geology being clear cut or not I actually think it is. Of course I'm not an expert but I do know a little bit about geology and my brother actually is a geologist- presently he,s in India but he was home for a week last week.
I showed him some of the web- sites on the Sphinx. He immediately said water erosion but then stopped himself and said hang-on it doesn't rain in Egypt.
I only say this to show that this isn't a big mystery to a geologist. Its like looking at a "U" AND "V" shaped valleys - its basic stuff. As you know Schoch hesitated because he thought it was too obvious an answer and assumed JAW missed something (p 226).
I've read Colin Reader, Alex's article etc. and they are good explanations but I can't find much wrong with Schoch at all. In fact Claire up until about a month ago I didn't even consider West's date - now I am.
Best,
John.</HTML>
