What to know about Archaeologists reveal secrets of prehistoric human-made island

Archaeologists from the University of Southampton and the University of Reading have used a new stereophotogrammetry technique to study a prehistoric human-made island, or crannog, in Loch Bhorgastail. Their findings indicate the site was established over 5,000 years ago, predating Stonehenge, and was used for communal activities across several millennia.

What happened

Archaeologists reveal secrets of prehistoric human-made island Sadie Harley Scientific Editor Robert Egan Associate Editor Archaeologists from the University of Southampton have excavated and recorded a large timber platform hidden beneath what today appears…

Why it matters

They used a technique called stereophotogrammetry to record the human-made island above and below the waterline as a single continuous structure, providing a perspective that wouldn't have been possible using land or underwater survey alone.

Common ground

The researchers, working with the University of Reading, examined the "crannog" in Loch Bhorgastail on the Isle of Lewis to reveal a structure built more than 5,000 years ago.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
