From ice

Have you ever been on a beach at the bottom of a cliff and looked up at the high-water mark and had the weird realisation that, a few hours ago, this place where you are standing was twenty feet under water and that, if you were to stay here for a few more hours, it and you would be underwater again? It feels like you have escaped drowning by the narrowest chance.

I had the same sort of feeling as I looked at the twisted steel framework emerging from the ice. Before the waters came, and the ice, I would have been standing on empty air beside one of the tallest buildings in London.
