Jammer:

No...the Sphinx and cemeteries were part of the package. Don't assume the head of the Sphinx being part of an "outcrop". Do some research and you will see the grain cutting through the head at a different angle than the body...that does not constitute an outcropping of stone.

Djedefre did as he was ordered, as did the rest of the kings. They had no choice in any matter regarding their personal pyramids...all were designed many years before Khufu was born...including Huni's

Best.
