below is a link to a narrated slide show presented by Robert Temple who believes he has discovered the location of no less than severn 4th dynasty or before pharaohs.
Also on the same link is a slide show from the Osiris shaft lasting 20 minutes which helps put into context the huge weight of the sarcophagus's that were lowered down into the Giza plateau.

here is a image of the valley temple with the Sphinx temple still hidden from view the Sphinx temple was not excavated until 1936 .

here is a image inside the Sphinx temple with what appears to be a hole in the bedrock.

here we can see a 100 ton worked piece of granite brought 500 miles up from Aswan and sunk into the bedrock of the temple.
you can also see that the granite block was sunk into the bedrock before the temple was constructed, as the temple wall is built over the top.


this image shows the block coming out of the north side wall of the temple.

this is one of three found on the Giza plateau and may have been used as a cable guide that fits into the recessed slot in the granite block, and was this how they lowered 40 to 60 ton objects safely down into their resting places.
i find this evidence quite compelling ,did a pharaoh die and after his burial have a temple built over his resting place ,have archoloigists mistakenly took this piece of granite as to only be a drainage channel, and as Robert Temple suggests it is actually a cable conduit.
if he is right and the tombs of Cheops and co are found in the locations that Robert has pointed too, then it's going to put a big question mark over the pyramids being built for their tombs is it not.
