In reply to mike barnard:
TBH this face is more perplexing than the Exit cracks.
The 2002 SMC Ben Nevis guide diagrams for this particular face are a bit vague to me ( sorry Simon ) , ideally a photo topo may show the lines more clearly but not all perhaps are visible from one viewpoint.
The best diagram I have at home is in the Kimber/ Cicerone 1994 edition page 114. Will scan you a copy.
I did Nordwand a day or two before Nordwand Direct and my earlier comments (22.07 on Sunday )about the routes do not need modifying.
Now, can anybody explain where American Pie goes?
