The Myris Challenge! Our beloved colleague Myris seems to think that all sensible geomorphologists would have a problem with my description of these bluestone boulders, slabs and blocks at Stonehenge as "typical glacial erratics" that would not look out of place close to any modern glacier front. There are plenty of other photos on the "Stones of Stonehenge" web site, here:
Look in particular at the photos for stones 31 to 49.......
So let's have a straw poll. Do YOU think these stones look more like ancient glacial erratics, or Neolithic quarried blocks?
