In reply to james mann:
As another bump to this and for general awareness, there was a large amount of loose rock in and around The Trench at Hartland Quay yesterday. It will have come down some time in the last 2 weeks, perhaps the same time as the rockfall at Cornakey. This area sees a lot more traffic than Cornakey (by both climbers and 'normal' people) so it's an important reminder to keep your wits about you in general on the culm!
