 The area has many old lead and copper mines that are now abandoned as well as having a large quantity of iron haematite, ironstone and ore. At the highest peak in Hartley stand nine obelisks referred to as "Nine Standards".Nobody knows the true purpose of the "Nine Standards" although some believe that they were used to create a sense of a forthcoming army to scare the enemy forces.However, it is believed more heavily that they were placed as geographical aid to help outline the borders between the two neighbouring counties, Westmorland and Yorkshire.
