Neolithic Humans Transported Stonehenge Altar 400 km, Study Shows

Summary

Story summary

Dr. Anthony Clarke published a study showing Neolithic people moved Stonehenge’s six-ton Altar Stone, not glaciers, with zircon analysis linking it to Caithness and Inverness-Black Isle in northeast Scotland 400 km away.
Ice-sheet modeling showed glaciers could not reach southern England, so researchers concluded humans hauled the stone across kilometres.
The team proposes routes such as the Berkshire Ridgeway with river or coastal transport, indicating Neolithic planning and social organization.

History

Historical Context

In the Fourth Dynasty, Pharaoh Khufu ordered the Great Pyramid (c. 2600 BC), mobilizing up to 40,000 workers to place roughly 2.3 million limestone blocks. Egyptologist Mark Lehner’s 1992 experiment showed wooden sledges on wetted sand cut pulling force by about 50 % and that 12–20 men could move a two-ton stone. The result parallels Dr. Anthony Clarke’s 2023 zircon study of Stonehenge, underscoring long-standing logistical skill.
