Some of the ideas discussed in this blog are published in my new book called "The Stonehenge Bluestones" -- due for publication on June 1st 2018. After that, it will be available by post and through good bookshops everywhere. Bad bookshops might not have it....

Oxford Gletscher

It's not often that one gets the chance to name a sizeable piece of Planet Earth, but was reminded that my colleagues and I once got to name a glacier in East Greenland.  It was previously unnamed, and we were the first to explore it.

This is another Google Earth image -- amazing quality.  Click on it to enlarge.  When we were there in 1962, the snout extended almost as far as the southern end of the trough -- there has been a phenomenal retreat since then.  This is a surging glacier, so behaviour is somewhat erratic, but the retreat is certainly down to global warming.

Look at the trimline running down the western side of the valley -- it shows with perfect clarity where the ice edge used to be, with moraine (greyish) below it and frost-shattered scree (brown) above it.  Here endeth the glaciology lesson for today.
