And thanks again, Caroline, I have a few things I want to add to the thread - and perhaps move some photos Roch added to their right place, and one that Grahame added - if it is OK with both?
Mike added some pictures, but also added some text and interpretation, so I cannot move those.
Where is Mike, by the way?
Edit to add: I cannot do anything about Roch, Grahame´s or Mike´s posts, only my own - it is fine!
