Wow, just wow.
I feel like jelly reading your report, that's some serious stuff.
I remember being on a family holiday many years ago where we got the train up to Kleine Scheidegg. I was only about 10 at the time I think. We only walked around a bit and went up onto the Glacier at the base of the Eiger but I remember being completely in awe of the size and scale of everything - unlike anything I'd ever experienced. (I wanted to climb up a bit or get the train to the top of the Jungfrau but my Dad wouldn't let me
Spoilsport ) but even from there it was incredible.
Not sure I'd ever have the balls to actually climb the thing!!
