Scientists solve mystery of the origin of Stonehenge megaliths
Scientists have solved a permanent thriller about Stonehenge, figuring out the native land of lots of the megaliths that make up the famed monument in Wiltshire, England, because of a core pattern that had been stored within the United States for many years.
Geochemical testing signifies that 50 of Stonehenge’s 52 pale-gray sandstone megaliths, often called sarsens, share a typical origin about 15 miles (25 km) away at a web site known as West Woods on the sting of Wiltshire’s Marlborough Downs, researchers stated on Wednesday.
The sarsens have been erected at Stonehenge round 2500 BC. The largest stands 30 ft (9.1 meters) tall. The heaviest weighs about 30 tons.

“The sarsen stones make up the iconic outer circle and central trilithon (two vertical stones supporting a horizontal stone) horseshoe at Stonehenge. They are enormous,” stated University of Brighton geomorphologist David Nash, who led the examine revealed within the journal Science Advances.
“How they were moved to the site is still really the subject of speculation,” Nash added. “Given the size of the stones, they must have either been dragged or moved on rollers to Stonehenge. We don’t know the exact route but at least we now have a starting point and an endpoint.”
Stonehenge’s smaller bluestones beforehand have been traced to Pembrokeshire in Wales 150 miles (250 km) away, however the origin of the sarsens had defied identification.

A sarsen core pattern, extracted throughout conservation work within the late 1950s when metallic rods have been inserted to stabilize a cracked megalith, supplied essential data. It was given as a memento to a person named Robert Phillips who labored for the corporate concerned within the conservation work and was on-site throughout drilling.
Phillips took it with him with permission when he emigrated to the United States in 1977, dwelling in New York, Illinois, California and at last Florida, Nash stated. Phillips determined to return it to Britain for analysis in 2018. He died this yr.

The researchers analyzed fragments of the pattern – harmful testing being off limits for megaliths on the web site – to determine the geochemical fingerprint of the sarsen from which it was taken. That fingerprint matched sandstone nonetheless at West Woods and all however two of the Stonehenge sarsens.
“I hope that what we have found out,” Nash stated, “will allow people to understand more about the enormous endeavour involved in constructing Stonehenge.”
