Experts confirm the source of rocks at Stonehenge, tracing the origin back to Pembrokeshire.
Research by National Museum Wales and Leicester University traces the source of some of the rocks that contributed to the masonry of the monument to "within 70m (230 ft) of Craig Rhos-y-felin, near Pont Saeson" (BBC News).
The BBC reports:
"For nine months Dr Bevins and Dr Rob Ixer of Leicester University collected and identified samples from rock outcrops in Pembrokeshire to try to find the origins of rhyolite debitage rocks that can be found at Stonehenge.
Researchers have previously suspected the origins to lie somewhere on northern Preseli Hills.

The BBC reports:
"For nine months Dr Bevins and Dr Rob Ixer of Leicester University collected and identified samples from rock outcrops in Pembrokeshire to try to find the origins of rhyolite debitage rocks that can be found at Stonehenge.
By detailing the mineral content and the textural relationships within the rock, a process known as petrography, they found that 99% of the samples could be matched to rocks found in this particular set of outcrops.Rhyolitic rocks at Rhos-y-felin, between Ffynnon-groes (Crosswell) and Brynberian, differ from all others in south Wales, they said, which helps locate almost all of Stonehenge's rhyolites to within hundreds of square metres.
Within that area, the rocks differ on a scale of metres or tens of metres, allowing Dr Bevins and Dr Ixer to match some Stonehenge rock samples even more precisely to a point at the extreme north-eastern end of Rhos-y-felin."
The location identified, archaeologists would now try and uncover how the stones actually reached Stonehenge.
