In reply to petegunn:
Mmm, see what you mean. Very convincing photo match.
I accepted Porcupine just because I remembered that we had certainly done it on the same day, but now that I think about it, "Black Icicle" does ring a very distant memory bell as well.
So my heartfelt apologies to tmawer who is the undisputed winner and route naming champ of the day.
Thanks
