Description: These large slate quarries were formerly worked as large open pits. The slate blocks were initially removed by blasting and then reduced to a manageble size using a mell (sledge hammer) and tully (long-handled wedge-shaped hammer) before being transported to the cutting sheds, sawn to size and riven into thin slates. The railway track and horse drawn wagons in the foreground lead to the Fisher Tunnel and Fisher Hill workings. The slates were brought to the surface using a long series of inclined trackways and water balance lifts. The slates were formed during the Early Devonian when a slaty cleavage was imposed on the Ordovician and Silurian rocks of the area. The best quality slate with the most even and regular cleavage was formed from the lithologically uniform mudstone successions.
