Tour de France - THE GEOLOGY!!! 

I wish I had come across THIS SITE a couple of weeks ago. If, like me, you find the Tour de France hypnotic, but occasionally get distracted by the glimpses of the geology and wonder what that is, then this is the site for you!

It describes, in a very simple way, the geology the race passes through. So you get an introduction to French geology with lots of nice diagrams and short essays about the interesting details.

There is an annoying map of the geology alongside the text - it is too small and the pop up rock descriptions are bigger than the windolet. Much better to go to the source of the geological map - Macrostat. Last week I mentioned the BGS Map Viewer; this site does a similar job for the whole world. Well worth looking at!
