Stonehenge Debate Shifts: Welsh Rock Challenges Ice Theory

Tiny Stone,Monumental Shift: New Evidence points to Humans – Not⁣ Ice – Moving​ Stonehenge‘s Bluestones

Salisbury Plain,UK – For​ decades,the question of how the bluestones⁣ of Stonehenge – the smaller stones set within the larger sarsen circle – arrived at their iconic location has been‌ a source of ‌intense debate. Now, a seemingly insignificant piece​ of ‍rock, unearthed‍ during excavations nearly a⁢ century ago, is dramatically shifting the consensus.⁢ New analysis of a⁤ palm-sized stone, dubbed the⁤ Newall boulder, strongly ⁢suggests that people,⁢ not‍ glacial activity,‍ were responsible‍ for transporting these‍ ancient stones over 125 miles from Wales.

researchers, lead by Dr. Richard E. Bevins of aberystwyth University, ⁣meticulously mapped the boulder’s mineral composition ​and chemistry, tracing its⁤ origins to Craig Rhos-y-felin in west Wales. This outcrop is a known source⁤ for ⁣the bluestones,⁣ but proving ‍ how they got to Salisbury Plain has remained⁤ elusive.

“The value of⁣ this particular stone is simple,” explains Dr. bevins. “As⁢ a standalone piece ​with a clear excavation history, it offers a fair test for the​ human versus ice⁢ question ⁤that ⁤has followed Stonehenge for decades.”

A ⁢Microscopic ⁣Clue, A Macro Impact

The newall boulder, measuring ⁣just 8.7 ⁤x 5.9 x 3.9 inches, was ‍originally excavated in 1924 by Lt Col Hawley. Re-examination using⁢ modern⁢ techniques revealed crucial details. Unlike stones transported by glaciers, ⁣the boulder‍ shows no evidence of glacial ⁣scratching.‍ Instead, its​ wear patterns indicate breakage and subsequent ⁣weathering – consistent with human handling and quarrying.

Microscopic analysis of the stone’s ⁣structure‌ revealed a‍ unique⁣ combination of minerals, including distinctive needle-like stilpnomelane and aligned titanite grains, matching the​ geological signature⁣ of Craig Rhos-y-Felin. ‍ Further geochemical analysis confirmed the Welsh origin, even accounting for millennia⁣ of burial in chalky⁣ soil. ‍ The boulder’s‌ shape also aligns with the dimensions ⁢of a‍ buried bluestone stump (Stone ‍32d) at Stonehenge.

Debunking the Ice Age Theory

The ⁢findings ⁢directly challenge the ​long-held theory that glaciers‌ transported the bluestones to Salisbury ​Plain during the⁢ last Ice Age. Regional geological surveys reveal ‌no evidence of glacial till, erratic trains, or moraine ridges in the area. ​ Furthermore, existing glacial evidence indicates that major ice advances flowed offshore into the ‍celtic ⁣Sea, a trajectory that wouldn’t have ​delivered stones to the Stonehenge site.

Instead, the ⁤team found evidence of human activity around the monument.Small ‍fragments of⁢ stone exhibiting​ sharp edges, indicative of ‍intentional “dressing” by humans,⁤ were ‌discovered.​ ⁣A natural ⁣scattering ⁣of rounded⁢ cobbles, which ​would be expected from glacial activity, was‍ notably absent.

A Living Landscape of Quarrying and Transport

The research builds upon previous archaeological work ‍at bluestone quarries in Wales, specifically at Carn Goedog ​and ⁣Craig Rhos-y-Felin. Excavations there​ have uncovered evidence of deliberate stone extraction,
