> Um... I'm not sure what argument you could use in Ilkley Quarry against chiselling given that it is a man made hole in the ground created by chiselling. Personally I'd be in favour of filling it in.
well that was kind of my point in to saying anything, it's man made and there are chippings from 1850 ish already. Still, I wouldn't and wouldn't encourage anyone to start knocking chunks out of it. Another case of just because someone has, it doesn't make it right to continue.
As far as filling it in, there are some excellent routes in there and it would be a massive shame to see them go.
