A new theory discussed by multiple outlets suggests that some of the large rocks used to build Stonehenge were transported from Scotland to Wiltshire during the distant past by glacier activity. Stonehenge is built from boulders that vary in size, with reported weights ranging from about 2 to 25 tonnes, indicating construction at a scale that would have been difficult without modern machinery. The central issue is that several of these stones do not match the local bedrock of the Stonehenge area, so their presence there requires an explanation for how material moved over long distances.
The proposed mechanism links the movement of the stones to glacier processes, which can carry heavy rock debris and move it across landscapes as ice advances and retreats. According to the articles, this approach is intended to account for both the non-local origin of the stones and the sheer weight involved. The theory is presented as a new explanation rather than a settled fact, aiming to address longstanding questions about the logistics of Stonehenge’s construction materials and their routes from Scotland.
