The Stonehenge Bluestones -- a problem for earth scientists?

Yesterday I gave a seminar in Aberystwyth University -- to a mixed group of undergraduates, research students and staff from various disciplines including glaciology, geography, geomorphology and geology. It was a good opportunity to explore some of my ideas with them, and to deal with questions and comments. Afterwards I had the chance to talk with Dr Alun Hubbard and his colleagues about the new modelling work they are doing -- with a view to refining the parameters and the "model-building" techniques allowed by modern computing power. It looks promising -- and Alun assures me that it should be possible, on the basis of a reasonably accurate map of ice limits in Southern England (from published sources relating to till / moraine localities) to work out what the glacier responsible might have looked like........

This is exciting -- and as I have said before, the problem of bluestone transport will not be solved by archaeologists, but by earth scientists. I hope my talk will have encouraged some of them to get involved, and to start looking at the field evidence that may help us to crack this particular nut.
