\n\tOnce thought to have originated in Wales, like the rest of the 4,500-year-old monument\u2019s bluestones, Stonehenge\u2019s altar stone has recently been traced through geological fingerprinting to Scotland. The question of how the megalith made the 435-mile journey from there to Salsbury Plain in England is now the focus of a study by scientists at Curtin University in Australia in collaboration with experts from Sheffield Hallam University, the University of Sheffield, Wessex Archaeology, and the University of Bristol in the United Kingdom. \u00a0Their findings were published June 4 in the Journal of Quaternary Science.<\/p>\n
\n\tStonehenge was built in stages by Neolithic and Bronze Age peoples between around 3,000 BC and 1,500 BCE. It consists of an outer circle and inner horseshoe of sandstone trilithons with inner arcs of smaller bluestones. The altar stone at its heart is thought to have been placed there during the second period of Stonehenge\u2019s construction, between 2,620 and 2,480 BCE.<\/p>\n
\n\tGeological evidence has confirmed that the monument\u2019s sandstone boulders came from the Marlborough Downs, 20 miles away, while its smaller dolomite bluestones were quarried in the Preseli Hills in southwest Wales, 180 miles to the northwest. The average sarsen (sandstone block) at Stonehenge weighs 25 tons; the average bluestone ranges from 2 to 5 tons, and the largest weighs 40 tons.<\/p>\n
\n\tUntil recently, there were competing theories as to how the stones traveled such long distances, with some positing that humans moved them by land or by sea and others suggesting they were deposited by glaciers during the Ice Age.<\/p>\n
\n\tEarlier this year, we reported that the Curtin University team had ruled out glacial transport of Stonehenge\u2019s bluestones, concluding that they were almost certainly carried to their present location through human labor alone. Now, building on their previous research, the Curtin and Sheffield Hallam University scientists postulate that the movement of the altar stone may have involved a combination of human and glacial transport.<\/p>\n
\n\tAfter studying ancient ice flows, the researchers believe that a glacier carried the altar stone from the Orcadian Basin in Northeast Scotland to Dogger Bank\u2014a prehistoric landmass connecting Britain to mainland Europe now submerged under the North Sea\u2014during Britian\u2019s last ice age between 33,000 and 11,700 years ago.<\/p>\n
\n\t\u201cOur modeling shows glaciers may have transported rocks part of the way during the last Ice Age\u2014potentially as far as Dogger Bank in the North Sea\u2014but not into southern England,\u201d says co-lead author Dr. Anthony Clarke, from the Curtin\u2019s School of Earth and \u00a0Planetary Sciences, \u201cmeaning the stone would still have needed to be moved hundreds of kilometers by people.\u201d He adds, \u201cTransporting a stone of this size over such a long distance would have required planning, coordination and a deep understanding of the landscape\u2014not to mention tremendous determination.\u201d<\/p>\n
\n\tSheffield Hallam University\u2019s\u00a0Dr Remy Veness, co-lead author of the paper notes, \u201cWhat is exciting about these findings is that they could imply that the people of Doggerland attached cultural significance to the Altar Stone long before it was incorporated into Stonehenge. . . . [The stone] must have been significant enough [for people] to be willing to move [it] at least twice; first to save it from being submerged by rising sea levels at the end of the last ice age and then again to its final resting place on Salisbury Plains.\u201d<\/p>\n<\/div>\n<\/div>\n
