Does this reason apply only to the Grand Gallery?
If so, then why?
This North-South orientation of the base and passages is found in all (?) Ancient Egyptian pyramids.
Have you any suggestions as to why this is?
I ask because, as I am sure you will agree, your '100 foot cliff' hypothesis does not, indeed cannot, apply to all of them.
Like it or not, the North-South orientation of the pyramids and their passages and chambers is down to a combination of religious beliefs and astronomy, and not the terrain they are built on.
This applies just as much to the Great Pyramid of Giza as it does to all (?) the other 90+ (?) pyramids in Egypt.
Question: are you wondering whether the availability (for want of a better term) of a '100 foot cliff' was the reason for the Great Pyramid’s architect uniquely (?) putting passages and chambers high up inside its superstructure?
