Well, this does present a problem doesn't it!
I have no reservations at all about walking on my own in out of the way places like this, but I'm not a fool, and walking across this would have been a pretty stupid thing to do. I don't think I'd have crossed this if I'd been with a crowd of people, never mind while I was by myself. The whole lot was frozen, and it was also much deeper and much steeper than it looks in this picture. Add this to the fact that I didn't have any crampons with me, then there was no way I was going to run the risk of breaking the ice and falling into the beck I could see running out from underneath the ice.
I didn't see the need to turn back, so I just headed straight up the fellside on the left hand side of the picture.
