In reply to Ron Rees Davies:
I think it was the bit to the left of the wall within. Not sure of the damage on routes, but went down into the gallery cave above the wall within and it was blocked off at the end.. just after the gallery.. I think I remember it being open last time I went down there.
There where some guys by the top of denorwig unconcrable who had just got out when it happen!
