A new study claims that the bluestones at Stonehenge were not transported to the site by humans but are instead the result of natural glacial movement. The research is based on an analysis of the Newall Boulder, a bluestone discovered at the Stonehenge site in 1924.
Until now, the overwhelming majority of archaeologists believed that Neolithic people quarried and transported the bluestones from the Preseli Hills in southwest Wales to Salisbury Plain in England, a distance of more than 200 kilometers. This theory was first proposed by geologist Herbert Henry Thomas in 1923 and was based on evidence of the stones’ distant origin and the possible engineering capabilities of the people of that time. He suggested that the stones were transported via rafts along rivers and then overland by dragging them on wooden sledges.
Dr. Brian John from Durham University analyzed the boulder and found facets and striations consistent with glacial movement, as well as worn surfaces and fractures indicating a process of abrasion and dragging by ice. The conclusion is that the location of Stonehenge was chosen not for religious intent or as a result of an engineering feat but simply because the stones were already there.
However, there are opponents to this claim. Additional studies conducted on the boulder by Rob Ixer, Richard Bevins, Nick Pearce, and David Dawson found that it matches Rhyolite Group C from the Craig Rhos-y-Felin area in north Pembrokeshire, and the striations thought to be glacial are actually internal structures of the rock.
