There is something very odd about the immediate area around G3's pyramid , ive mentioned this before but no one has offered a plausible explanation for why they went to great pains to cut into the bedrock in the fashion we can observe.
I am talking about the square block arrangement that is clear to see on the West side of G3, even clearer from the above shots ive provided below , two from Airpano , and one from Google Earth.
So far ive only found one mention of this peculiar area, and that comes from Petrie, who says Perring found the substructure of G3 to made of Megalithic Blocks .
From Petries [www.ronaldbirdsall.com]
" But the pavement seems most probably never to have been placed around the Pyramid , Perring found nothing but a substructure of rough megalithic blocks, with wide joints, and concluded that it was to be covered with finer work.
So in view of our discussion on G3's anomalous internal configuration that may or may not be indicative of a design change , i am now wondering if this block area that seems to extend out to the West by a further 110 ft from the base of G3 (see arrows in pic that delineates a line in the sand that may mark the edge for this blocking) is an indication of a plan for a much bigger pyramid , this blocking does not extend out beyond the South base line, as clear photography shows G3's base line just a few feet from the edge of the Plateau on clear bedrock.
Again it does seem they couldn't quite decide what size G3 was going to be, then someone found the original blueprint for Giza
