In reply to c8:
Pindale Quarry, Not even Gibson got his Hilti out for this one!
Stannington Ruffs, I'm quite fond of it as a pleasant woodland spot.
Padley Quarry, Like Stannington its not a bad spot, just needs a clean to spruce up the climbs.
Birch Quarry, The VD arete is actually a really nice route, as is the wall to its right. (the only vaguely climbable rock in the place)
Granitethorpe Quarry, More like it! Pool full of detritus, overgrown and fenced off with access down dog$hit lane. Still lacks that urban squalor factor.
Carvers Rocks? Southern sandstone comes north but leaves the quality behind.. in a nature reserve though so instantly disqualified.
Laddow, are you serious? Whats a bit of Green?
I'm sure many of the Swansea area quarries are very squalid (the dead dog with its guts out mentioned in the Gower guide makes Penrhiwceiber quarry sound worthy) but I don't know any of them, so I'll nominate..
Chatterton lane quarry. Full of rubbish, disused rifle range, overgrown and I didn't even tick the diff. (The arete looks quite good though).
