A GALLERY OF THE SOURCES OF THE STONEHENGE BLUESTONES, ACCORDING TO RECENT GEOLOGICAL RESEARCH
These identifications are in the work of Richard Thorpe and others in 1991, and Olwen Williams-Thorpe and others in 2006. There has been other work by Dr Rob Ixer and others. Some of this new work is reported on the "Stonehenge Thoughts" blog. Twenty different sources have now been identified, and some are still unknown. Recent work has centred on a site called Craig Rhosyfelin, near Brynberian -- now established as the source for much of the rhyolite debris at Stonehenge.
