Summary from English Wikipedia (enwiki)

Graig Ddu quarry (also known as Craig Ddu quarry, Manod quarry, or, since the closure of the nearby Cwt y Bugail quarry, Cwt y Bugail quarry) is a disused slate quarry near Blaenau Ffestiniog (formerly Blaenau Festiniog), in Gwynedd (formerly Merioneth or Merionethshire), North Wales. Although output was only about 3,000 tons a year (3,140 tons in 1882), it reputedly has 36 saw tables and the same number of dressing machines on site. As with others in the area, the quarry suffered from a lack of water, resulting in the siting of the mill some distance away, at a lower level.
