Not to beat a dead horse, but
If, as commonly believed, the Surrounding Ditch of Stonehenge were nothing
more than a quarry for the material for the building of the Surrounding
Bank, can anyone suggest a practical reason why the diggers of the Ditch,
1. left 'barriers' of the natural chalk extending fully across the bottom
of the Ditch and separating the segments of the Ditch from each other and
2. why the barriers had a `a layer of clay over and at the sides of them' and
3. why these barriers, that stand as high as three feet above the floor of
the Ditch, occur only in the sloping south quadrant while there are none in
the level east quadrant?
Are there other examples of 'quary ditches' having such barriers?
There is no prize for the best answer, but there may be more questions about
other features of the Ditch.
Something to think about,
