[3] A north connected siding was provided for the quarrying operations run by H. Austin in 1945, which later (in 1974) involved the removal of the down platform on the railway line (for trains northwards serving Carlisle).

[8][9] In an effort to combat the effects of acid rain caused by pollution, limestone would have been added to power station gas-flues, absorbing the sulphur.

[12] The company that owned the quarry (Hanson) turned the site over to English Nature in October 2000, in the expectation that it would reach peak re-wilding status by 2040.

[13][14] A stone bench known as the Geology Seat has been constructed inside the quarry, which is on a path linking Ribblehead with Selside.

Visitors are encouraged to sit down to listen to an audio recording describing the geology, wildlife and history of the area.
