humans not glaciers moved stonehenge rocks geological study 1234771264

Researchers at Curtin University in Australia have published a study in Communications Earth and Environment providing geological evidence that humans, not glaciers, transported the massive stones used to build Stonehenge. The team tested sediments from streams near the monument and found no signs of glacial activity during the Pleistocene, ruling out the theory that ice sheets carried the megaliths. The stones, including sandstone boulders from the Marlborough Downs and bluestones from Wales, weigh up to 40 tons, but exactly how ancient peoples moved them remains unknown.
