Stonehenge Rock Source Identified

Scientists have found the exact source of Stonehenge's smaller bluestones. The stones' rock composition revealed they come from a nearby outcropping, located about 1.8 miles (3 km) away from the site originally proposed as the source of such rocks nearly a century ago.
The discovery of the rock's origin, in turn, could help archaeologists one day unlock the mystery of how the stones got to Stonehenge.
