I have two, that whilst I don't know a thing about it I feel are equally worthy of consideration :

1. Reverse osmosis: as the water from Swallowhead Springs induces the pukes & shits and the Winterbournes dry up, a reservoir was dug, but this didn't hold enough water for the annual FA cup final held at Avebury, so a bigger reservoir was built, it was during this process that water was noticed to be springing up and filtered by the chalk, so a huge water filter was built so there was plenty of water and the world cups could be held at Avebury, only a new B&Q opened at Stonehenge with bluestone decking so everyone left and then the Romans took it over as a spa resort with water skiing pulled by chariots.

2. Slime : it is meaningless residue and academics that managed to foist an unnecessary tunnelling job on a precious ancient monument deeply loved by the public will have eternal reputations assured and numerous PhD's will be produced about it that no-one will ever read.

As I say, they are just ill informed theories.

VBB :o)

Agreed, Squid. The way I see it, the whole area about Silbury; widely referred to as "The Moat" and (I think) by Dames a "The Mother figure" seems to indicate a lot of deposition anyway. Reference to the Figure I mentioned in my previous post shows the alluvial band (yellow) as being quite broad and accomodating Silbury III's broad base within it. So I was wondering if this band was just an extension of what was already there. IMO, the notes in the PDF (and my imagination in translating them) don't seem to clarify anything. Which is why I asked. I'm glad I did, because I like your interpretation.
