A groundbreaking new investigation, spearheaded by archaeologists from Curtin University and Sheffield Hallam University, posits that Neolithic individuals, rather than glacial forces, were responsible for relocating the Altar Stone—a prodigious six-ton sandstone megalith central to Stonehenge—from its origins in northeast Scotland to Salisbury Plain.

“Our discoveries strongly indicate that this expedition was far from straightforward and almost certainly necessitated meticulous foresight across several distinct phases,” stated Dr. Anthony Clarke, a distinguished researcher associated with Curtin University.
“Contrary to being passively conveyed by ice, the available indications point towards a deliberate, painstakingly orchestrated movement across a challenging and diverse terrain.”
“Our simulations suggest that glaciers might have facilitated the rock’s journey for a portion of the distance during the preceding Ice Age—potentially reaching as far as Dogger Bank in the North Sea—but their influence did not extend into southern England. Consequently, the stone would still have required human intervention for transit over hundreds of kilometers.”
“The investigation reveals a notable absence of feasible glacial pathways that would directly connect the source area to Stonehenge, thereby solidifying the assertion that human transportation was an indispensable requirement.”
“This evidence instead implies that the stone was likely transported incrementally, possibly by integrating overland hauling with navigation along rivers or coastlines wherever feasible.”
Within the scope of this study, Dr. Clarke and his esteemed colleagues integrated mineral dating techniques, sophisticated geological provenance analysis, and computational simulations of Ice Age ice-sheet dynamics to meticulously examine the mechanisms by which Stonehenge’s Altar Stone arrived at Salisbury Plain.
Initially, they precisely identified the stone’s geological origin as northeast Scotland by meticulously scrutinizing its mineral composition and age markers.
Subsequently, they developed models depicting the behavior of ancient glaciers, concluding that ice could indeed have transported the stone in a southeasterly direction towards Dogger Bank, a geographical feature now submerged within the North Sea.
Building upon these findings, the research consortium put forth the hypothesis that prehistoric peoples might have subsequently retrieved the stone from Dogger Bank and conveyed it to Salisbury Plain, where it was ultimately integrated into the iconic Stonehenge monument.
“These revelations highlight a remarkable degree of organization and collaborative effort among Neolithic communities that had not been fully recognized previously,” Dr. Clarke remarked.
“The logistical feat of transporting a stone of such immense dimensions across an extensive geographical expanse would have demanded considerable foresight, adept coordination, and an intimate comprehension of the surrounding environment—not to mention extraordinary levels of resolve.”
“This research effectively demonstrates the potent synergy achieved by combining rigorous geological analysis with advanced computational modeling in resolving enduring enigmas surrounding the construction of Stonehenge.”
“Future scholarly pursuits are slated to focus on precisely locating the Altar Stone’s definitive provenance within northeast Scotland and conducting further in-depth investigations into the potential transportation routes utilized by these prehistoric societies.”
The pertinent findings are now published in the esteemed Journal of Quaternary Science.
