When we were here a year or two back we had a reasonably thorough look at the levels to the south of the long tunnel.
Through a mixture of sun-induced apathy and nettle stings most of the group didn't wander over to the northern side of the valley to see what was there.
The question is, should we have done and is there enough there to justify a return trip bearing in mind its a four or five hour drive? The plan on here certainly suggests that there should be though in such heavily wooded ground things can be hard to find and often obliterated entirely.
Second question, is the Slates from Abergynolwyn book worth the not inconsiderable sums being sought for it? Is it a book on the actually quarry and its working or is it more re the community like the Ratgoed book?
Cheers!
