>"By the way, I do not believe that these grooves are primarily the result of water-erosion. But it's of course possible they were enlarged secundarily by different kinds of erosion."


These midpoints would tend to channel water preferentially to
the rest of the side but this would not be a strong effect even
as they wore deeper. I agree that it's improbable they are the
result of ambient water erosion.

These sides would also tend to channel wind and it would increase
as time went on. However the amount of channeling is so small it
seems most improbable that this is the cause. It seems likely
that these were either design features or are the result of wear
which occurred during construction.

A close inspection of some photos will reveal less prominent grooves
which are parallel to the large groove and midway to the pyramid at
the base. These are on either side but only on the north face. If
these are counterweights then it's logical to assume this west count-
erweight was used as an elevator for men and supplies since the men
were barracked on the west side.
