Stonehenge tunnel survey reveals new sites, and mysteries

Archaeologists are mapping the area before road is replaced and teasing secrets from the ancient landscape

Some 3,400 years before the roaring torrent of the A303 road sliced the Stonehenge landscape in half, some people cut a beautiful pit a metre deep into the chalk with no tools except picks made of red deer antlers.

They may have had primitive tools, but there was nothing primitive about their skills: the bottom of the pit was so neatly levelled that you could balance a beaker of mead on it without spilling a drop.
