Recent research suggests that the Altar Stone at Stonehenge may have originated from Scotland, not Wales. This discovery indicates that ancient Neolithic groups had connections over long distances, as reported by Bruce Bower in the article “Stonehenge’s roots extend to Scotland” (SN: 9/7/24 & 9/21/24, p. 10).
While this theory is intriguing, geoscientist Anthony Clarke from Curtin University in Australia believes it is unlikely. He explains that ice sheet movements show glaciers moving northward from central Scotland towards the Orcadian Basin in the northeast, where the Altar Stone is believed to have originated. Therefore, it is improbable for glacial activity to transport the stone south to Stonehenge.
In addition, there is a lack of glacial erratics – rocks deposited by glaciers – in central southern Britain according to Clarke. Specifically, there are no Scottish erratics near Stonehenge.
A fascinating phenomenon involving cloud-forming aerosols during stratospheric air intrusion events was detailed by Carolyn Gramling. These events occur when Earth’s jet streams cause stratospheric air to dip into the troposphere below as described in “Earth’s jet streams sow cloud seeds” (SN: 9/7/24 & 9/21/24, p. 12).
