Ice and ingenuity: Glaciers and ancient people moved Stonehenge's Altar Stone

A Curtin University-led study using geological analysis and ice-sheet modeling suggests Stonehenge's Altar Stone originated in northeast Scotland and was carried by glaciers about 200 miles to Dogger Bank, after which prehistoric communities hauled it roughly 250 more miles to Wiltshire, for a total journey of about 450 miles — implying a carefully planned, multi-stage transport rather than ice doing the whole trek.
