Dem bluestones | The Times: "Contrary to a recent archaeological report, the arguments for the Stonehenge glacial transport theory still stand
Sir, It is misleading to suggest that new evidence on bluestone provenance freezes out the Stonehenge glacial transport theory (Norman Hammond, “Bluestones glacier theory is now frozen out”, Dec 17). Many bluestone types at Stonehenge do not match the Pont Saeson outcrop. The arguments for glacial transport still stand: varied bluestones, many sources, and glaciers capable of removing large erratics from Pont Saeson and other areas.
