How much do we know about Stonehenge? Less than we think. And what has Stonehenge got to do with the Ice Age? More than we might think. This blog is mostly devoted to the problems of where the Stonehenge bluestones came from, and how they got from their source areas to the monument. Now and then I will muse on related Stonehenge topics which have an Ice Age dimension...

Finding the GBG ice edge
The two maps above show ice movements during earlier glaciation(s) of eastern England, with "British" ice from the north pressured eastwards by Scandinavian Ice coming in from where we now have the North Sea (which was not there at the time). Note that the ice edge is almost as far south as London.
These two UK maps are of limited use, since they relate to the Last Glaciation. There is now great dispute as to where the southernmost Devensian ice limit might have been, following the discovery that till on the Scilly Islands is of this age. (Thanks to Clark, Gibbard and Rose)
