We can see best path to G1 is like I have suggested in previous threads at the right of the Sphinx harbor where the modern road is today:
It is the logical solution, isn't it?
I know that the majority of opinion is that to move heavy loads, a causeway was necessary. However, at places such as Baalbek, no causeway has been discovered which may have been used to move the megaliths from the quarry to the temple. Therefore, the absence of a construction pavement does not rule out the possibility of that route. Perhaps, a smoothly surfaced bedrock could suffice.
As mentioned, Houdin believes that he has discovered a causeway linking Khafre with Khufu.
Regarding the Wall of the Crow, it seems to be related to the waterway. It is interesting to think there may have been a bridge over the waterway from one of the "islands" leading to the Wall of the Crow.
Possibly. However, one needs to scrutinize the foundations to be certain of their depth with relation to dynastic water levels. The underpass gives me pause with regard to water. What would its use have been? It's of a similar width to the causeways.
I haven't quite figured it out yet, but I am stuck on the idea the Sphinx enclosure was part of this process before the Sphinx was carved into a statue.
The sphinx is not essential to the Giza plan. I think that too much emphasis has been attributed to it. It's artistic. Not architectural, mathematical, astronomical, stellar (maybe - faces East}. Could be a guardian of the site. It just seems that the site of the mound was fortuitous. But, it could well have been of a significance either forgotten or ignored and kept to be recarved by a self important pharaoh.
