Blocks Fitted into Solid Bedrock?

One of the features of plateau which has been noted by some, but in my opinion has yet to be adequately explained, are round limestone plugs about 25 cm wide set into the bedrock on the East side of the Chephren pyramid. Indeed, I do think it entirely possible that these plugs were fit into holes which originally served as the underpinning for some device connected to the building of the Chephren pyramid. But this is mere conjecture. What were the original builders really up to with all of the strange cuttings and fittings that they made in the bedrock along the South East side of Chephren? There is a wonderful mystery here laid bare for all to see. Keeping in mind that originally all of these plugs, cuttings and fittings of odd shapes would have been entirely hidden beneath the terrace stones which were laid tightly over top of these anomalies.

Above one can see the odd collection of plugs set into solid bedrock on the East side of Chephren. It has been noted that the round plugs in particular can be found at various distances from the pyramid based possibly indicating a pattern which mirrors the size and shape of the pyramid’s side. What purpose, however, was being served by all the other odd shaped stones set into the bedrock with great precision, seen here in combination with some of the round plugs?

Shot of a very non-uniform rectilinear stone set into the bedrock. Ridges and undulations of the surface here, now extremely worn, indicate to me the remnants of the same technique for anchoring the terrace stones around Chephren that was used for the terrace stones of The Great Pyramid.

In the same vicinity as the stones above one finds this “corridor,” “pathway,” or “covered passage?” Here the bedrock has been cut in precise but in places awkward angular shapes to receive stones which follow one next to the other in succession. I don’t believe for minute that these cuts and fittings were done with copper chisels. The work to do so and acheive such perfection is hardly something one would take on at a whim; an enormous effort would have gone into it. But to what purpose?

The same pathway as above continuing with very straight stones.

The beginnings of this pathway are filled with sand. If beneath the sand one was to find but the flat bedrock into which these stones were fitted, one must ask exactly what was the purpose of all this work? Notice here the very odd offshoot cut into the bedrock in the right side of this frame.
