How much do we know about Stonehenge? Less than we think. And what has Stonehenge got to do with the Ice Age? More than we might think. This blog is mostly devoted to the problems of where the Stonehenge bluestones came from, and how they got from their source areas to the monument. Now and then I will muse on related Stonehenge topics which have an Ice Age dimension...

The Gower raised beaches
I came across these and other splendid images on Jessica Winder's blog site, which can be found here:
https://natureinfocus.wordpress.com/2013/01/01/ancient-gower-shells-raised-beaches/
They are reproduced here with her kind permission. She has 20 photos from the Gower raised beaches in this file, from a number of different sites. Many of these deposits are cemented, and the main species of shell are Patella and Littorina.
There used to be references to "the Patella Beach" and "the Littorina beach" and there was an assumption that they were at different altitudes. Nowadays it is assumed that all the beaches date from the last (Ipswichian) Interglacial, around 130,000 - 100,000 years ago.
