In reply to Stephen Reid: Is this the Dennis Davies that led the first succesful ascent of Nuptse in 1961? Although I think that was spelled Davis.
I climbed with him once or twice if it was, he is no longer in the CC members list so that could mean one of two things.
The only lead I can offer is try Pip Hopkinson on
twodonline@btinternet.com who introduced me to him or the CC if he is in the obituary list.
