Ravensdale bird ban has been extended by 2 weeks to 14th July. This isn't showing on the UKC logbook page and was only updated on the BMC RAD yesterday. We only found out half way up a route as someone walked up to the base of Raven Buttress after turning up to put post an update at the start of the walk in path. We did lower off. Thought this might save others from a wasted trip.
