Sorry Nigel -- I thought we were supposed to be arguing out where the weight of evidence lies? All 4 theories can't be right -- at least not in their entirety. Probably what we'll end up with is a classic compromise, with ice doing some of the work and man the rest.

Would you not agree with me that the archaeology establishment has worked rather hard at making sure that their sacred cows remain sacred? Look at the way Kellaway and Williams-Thorpe were ignored and vilified by men who should have known better, just because they dared to question the established belief system of our leading archaeologists........ Richard Thorpe and his colleagues put forward meticulously researched geological evidence in 1991. They have never had the credit they deserved, for their contribution to a full understanding of Stonehenge.
