That's what I thought too.

The rather condescending remarks by the geomorphologist, Dr Brian John, to the effect that he, "... always thought the idea that Bronze Age man had quarried the stones and then taken them so far "stretched credibility." and that, "Much of the archaeology in recent years has been based upon the assumption that Bronze Age man had a reason for transporting bluestones all the way from west Wales to Stonehenge and the technical capacity to do it."* beggars belief.

For heaven's sake, Dr John, if the builders of Stonehenge had the vision and technical capacity to create Stonehenge in the first place they would surely have had the capacity to get the bluestones on site from basically wherever they wanted. Perhaps Dr John needs to visit Silbury and see what people a few thousand years ago were capable of in terms of 'technical capacity'.

Precisely.

Unless they are seriously sugesting that the builders of Stonehenge used every single scrap of glacially deposited Bluestone in Wiltshire (Which is even more outlandish an idea than the Bluestones being transported from Wales), their theory rather relies on deposits of Preseli Bluestone being found in the south west of England, rather in the same manner as the Greywethers.

Have such deposits been found? If so they would also have to be bleedin' obvious or else the builders wouldn't have found them in order to use them.

They found a bluestone inside a longbarrow. Aubrey Burl says:

"Following his excavation of Boles Barrow of 1801, William Cunnington wrote of the barrow's `large stones' amongst which he discovered a `Blue hard stone ye same as the upright Stones in ye inner circle at Stonehenge'. For his period, Cunnington was a competent geologist, well able to distinguish between sarsen and dolerite. He removed ten stones from the barrow and arranged them in a circle in his garden at Heytesbury. After his death, a bluestone was taken from his garden to Heytesbury House. From there, it was given to the Salisbury and South Wiltshire Museum by Siegfried Sassoon in 1934."
