There's another way of looking at this, in some barrows, and shafts, ritual goods (and according to Burl, soil as well) from a previous site can be brought to be deposited as an offering... so that, as at Maumesbury Rings, the shafts had "antique" pieces of pot on younger pieces of pot disturbing the image of sequential layering...(But .... isn't there also just a bit of a chance that the Stonehenge bluestone circle was first erected in Avebury and was then moved to Stonehenge?...a tenth of the effort subsequently used on the sarsens. Or was he wrong, was this Bluestone not bluestone? Did it go missing?)
The internal walling bit is interesting, Someone called Gray in the 19th C wrote a very long report on Wick Barrow, Storgusey, which also had a beautiful interior wall surrounding the mound, in the sense that soil was piled up against it as soon as it was built....
