I agree about Hawass. Schock not so much. I think Temple’s explanation for much of the erosion is more plausible.
BTW, have you heard anything about Temple? He seems to have either disappeared or passed away with no notice. He’s published nothing in 10 years, despite mentioning a possible book on Abydos and the Tomb of Osiris which he was given permission to explore.
Exploration would mean a supervised visit, if Hawass had anything to do with it. Otherwise, academic affiliation (and presumably kickbacks) or visit as a tourist which is what the late J.A. West used to do when he conducted his occult tour of Egypt.
