In reply to Sl@te Head:
It's a huge one, I dont think its done that much damage to the routes, I think the start to a small rusty nail on a large mantlepiece is gone, and the wall within is still OK I think (havnt been there, just reports from friends who have). The hut in the bottom is wiped out it got cut in half by a boulder. I've spent a few nights there good job it didnt happen then.
