In reply to ebdon:
Thanks! I think it's been debated before, that quarries heavily blasted for bulk products like limestone for cement or hard rock for road grit make terrible fractured rock for climbing. I did some access work back in the day (catch fence) and some stuff on some sites was a shattered fractured mess.
If you could ask them to minimise the charges and pry off blocks with crowbars, rather than blast and load, we'd be eternally grateful as it'd be very climbable.
The rumour, which is possibly just that and not based on fact? (can you confirm?) is that the shale on site may become uneconomic to extract as quarrying progresses, which in turn would spoil the economy of cement production on site. As mentioned it might be total nonsense though, so any actual facts on that would be appreciated.
