The view above shows the waste heaps. Each one would have had a rail track along it for the wagons to go on, to tip the waste over the edge into the used part of the quarry.
We had finished the steepest part of the climb but were still only halfway up! We alarmed dozens of grouse and partridge and a rabbit or two as we trudged up through the heather.
Yes it is a grouse, but digital cameras are slow to start and so most of them got far away before I could aim and focus.
Lead was also mined from seams running through the limestone. This old adit would have followed a seam into the hillside until the lead ran out. It seemed to have been a bivouac for more than one person over the years.
