In reply to goldmember: The forthcoming Rockfax will cover:
Areas Included - Llandudno Ormes, A55 Crags, Ogwen (Idwal, Tryfan), Carneddau, Llanberis Pass, Snowdon (Cloggy), Llanberis Slate Quarries, Anglesey (Gogarth), Betws-y-Coed, Gwynant Valley, Moelwyns, Cwm Silyn, Tremadog, Lleyn Penninsula, Mid-wales (Cader Idris)
Which will definitely include classic and good new slate routes. Not comprehensive, but a good deep selection, including much of the new stuff.
Ground Up are publishing a slate guide book that will give definitive coverage to the quarries.
Cheers,
Jack
