Albert Hargreaves:

To take out 130 feet of line on to this entirely virgin face up a steep, loose and grassy wall, tremendously exposed, with no knowledge of what difficulties lay in the 600 odd feet above, was surely mountaineering courage of the highest order. And it must have required the utmost skill and route-finding ability, as well as courage, to finish that climb. Despite the many more difficult shorter routes that have been done "unseen" I think this expedition will stand out in the history of British rock-climbing as a most important event. [1]
