It has been suggested by some sources that the cladding actually
fell off in an earthquake. More was taken off to rebuild the near-
by areas so it could well be a staging area or even an attempt to
find the king's actual burial chamber or a path to it.

The cladding was reported to have been inscribed with enough mark-
ings to fill 10,000 sheets of papyrus. Today none of these mark-
ings are known despite their continued use as parts of building in
the area.

One has to suspect that the designers were well aware of the region's
propensity toward earthquakes and intentionally made the stone so it
would collapse. The sometimes cited idea that the sheathing might
have caused the tracks seen on all four faces is ludicrous in light
of the fact that each side is already bifurcated and removing the
sheathing would be a dangerous and difficult process. It would not
have been taken to the center and dropped down.

This bifurcation was not readily apparent until aerial photography
was available though I believe Petrie was aware of it.

It is not only part of the solution to how it was made but to why as
well.
