Horse Crag Quarry
Horse Crag Quarry is an old slate quarry up with underground workings on the Tilberthwaite Deep Adit Level.
The ruins of the smithy and site office of Penny Rigg Mill stand at the entrance to the quarry with a few iron remains of machines and an old compressed air hose leading into the underground closehead.
The closehead or underground slate quarry not too far inside the adit here was worked later by John W. Shaw and with machine drilled shotholes using compressed air from the hose still in-situ. Shotholes in the deep level adit are found to have been hand-drilled.
