Slate Quarrying
As well as lead and copper mining, quite a large undertaking of slate mining has been taking place over the years. Pets Quarry, currently being worked by "Kirkstone Green Slate Company" is just before the highest point in the pass, from Ambleside. Caudale slate mine is a few miles further down, on the Ullswater side, and was last worked at the beginning of the 20th century. All adits to the mine are now blocked. Nearby is the Hartsop Hall Lead Mine.
