In reply to SOUTHERN GRAY:
I totally agree. Absolute vandalism. If the 'winter climbers' who scratched their way up some of these Gable classics returned in summer, I think they would probably feel ashamed of their ascents when they saw the damage done. Gable crag is one of the best rock climbing crags in the Lake District. One a summers evening catching the setting sun you can't get better.
I have climbed Jabberwock in summer a few times and I can't remember any drainage, vegetation or turf that in my eyes would make it a winter climb. Although I totally oppose winter ascents of Engineers Slab, at least the upper groove is a drainage line that would be iced up in winter.
