Sad news that this unique archaeologist has died a few days ago. He moved to my favourite part of Wales, somewhere near the Prescelis, and conducted digs at both Stonehenge and this part of Wales - the famous bluestones.
There is a lovely gentle video of him explaining his thoughts and perhaps this is the way we should remember him, alive and vivid on a Welsh hillside.
