Belayed by Trevor Peck and watched by Barrie Biven. Photo by Roger Bacon.

Surely one of the most iconic photographs ever taken in British climbing and such a worthy front cover of 'High Peak'. Epitomises 'the leader must not fall' ethos. The tension is marvellously captured, Trevor Peck standing ramrod straight, Barrie Biven's hands on the rock (almost in sympathy - wonderful), Peter Biven at, I guess, the fateful moment of, "Do I turn back or do I commit irrevocably?"
For me, this photograph and John Stainforth's equally iconic one of John Syrett on Wall of Horrors say it all about gritstone commitment.

From the front cover of High Peak by Eric byne I think - great photo, great book

Mick Ward's Barthesian interpretation is superb. This is the natural precursor Bernard Newman's wonderful photograph of Steve Bancroft on Strapadichtomy. I started climbing in the mid 1970s, in the Leicestershire slate quarries, and at the time the Biven routes were still the 'to do' routes: bold and brilliant.
