many lines were climbed at roseness and tomb of the eagles in the 70's by mick tigheand the marines. and then many lines were done at both places in the 80's by alan mcleay and friends.none of them were recorded or registered with the smc ,so bear in mind that any 'new' routes that you record have propably been done already,it would be respectfull to mention this if you intend to register them with the smc.the same will apply to yesnaby esp for the mid/lower grade routes.
