I like the blue as well, but I have to admit that the first thing that springs to mind when I see blue ice is coldness. By the time I took the picture, the sun was out in full force, as testified by the blue sky. It wasn't windy and that made it very pleasant to be up there.
A few hours earlier, on our way up in darkness, it was a different matter. It was very cold indeed. At one point, after a steep pitch, we had to sit down on a small ledge to try and get some blood flowing into our hands again. I took off my mittens and stuck my hands in my armpits, under my down jacket, and it must have taken close to 15 minutes to get them warm. Next time I do something like this, I definitely need warmer gear!
Frankly, I wasn't worried at all about the seracs coming down on me. Just enjoying our successful climb, and at the same time focussed on not slipping and tumbling off the mountain. I mean, if you fall here, you've got to self arrest very quickly!
