New glacier theory on Stonehenge

"A geology team has contradicted claims that bluestones were dug by Bronze Age man from a west Wales quarry and carried 240 miles to build Stonehenge.



In a new twist, Open University geologists say the stones were in fact moved to Salisbury Plain by glaciers.

Last year archaeologists said the stones came from the Preseli Hills.
Recent research in the Oxford Journal of Archaeology suggests the stones were ripped from the ground and moved by glaciers during the Ice Age.

Geologists from the Open University first claimed in 1991 that the bluestones at one of Britain's best-known historic landmarks had not come from a quarry, but from different sources in the Preseli area.

The recent work was conducted by a team headed by Professor Olwen Williams-Thorpe, who said she and her colleagues had used geochemical analysis to trace the origins of axe heads found at Stonehenge and this backed up the original work. "
