Stonehenge Discovery Radically Changes Understanding of Ancient Monument

Researchers from the Universities of Birmingham and Ghent have identified thousands of pits around the ancient monument of #Stonehenge. Archaeologists combined the first-ever electromagnetic induction survey of the area with evidence from more than 60 boreholes and 20 targeted excavations via computer analysis. The largest pit — which was 13 feet wide and dug some 6.5 feet into the chalk bedrock — is notable for being the oldest trace of human activity discovered on Salisbury Plain to date.
