I found this on Stridingedge.net:
"Looking across Pike de Bield to the Scafells. Further along from Pike de Bield is a large cairn (marked 'memorial cairn' on 2nd edition Wainwright's), the brass plaque on it says 'Gerry Charnley 1929 - 1982."
It is strange he did not take a photo of it. My Wainwright is a first edition re-issue.
