 Unlike the adjacent Caldbeck Fells, which were heavily mined for minerals, the Uldale Fells have only ever had one mine on them and that was on Longlands Fell.The Longlands Fell copper mine operated in the second half of the 19th century but was soon found to be uneconomical and abandoned, one of the levels is now dammed to provide water to the village of Uldale.Just to the north of Longlands Fell on the adjoining small Aughtertree Fell (300 metres) are signs of an Iron Age farming settlement first settled 3,000 years ago and probably deserted during the Dark Ages.
