The Wiltshire, England, site harbors evidence of ancient occupation, with traces of pine posts raised about 10,500 years ago. The first megaliths at Stonehenge were erected 5,000 years ago, and long-lost cultures continued to add to the monument for a millennium. The creation consists of massive, 30-ton sarsen stones, as well as smaller bluestones, so named for their hue when wet or cut…

The new findings raise more questions than answers about how the rocks could have made it to Stonehenge.

But pinpointing the exact location of the stones’ origins could help archaeologists looking for other evidence of ancient human handiwork near the area, which could then shed light on the transportation method, Bevins said.

“For example, if we could determine with confidence that the stones had been worked by humans in Neolithic times, then the ice-transport theory would be refuted,” Bevins said.
