Force Crag Mine

Coledale's most notable feature is Force Crag Mine; the buildings, spoil heap and associated structures of which are practically the only sign of human influence in the upper valley.

Mineral workings may date back to 1578 in the valley Significant workings did not begin until the 1800s with lead and silver being mined until 1865, ending with a drop in the price of lead rendering it uneconomic. Later Barytes was mined, with 5300 tons of ore being produced up to 1879 when again market forces led to production ending. The mine was worked on and off with various changes in operation, and under different owners, with lead, barium and zinc ores being extracted. In 1990 a collapse in the mine led to it being closed, and ownership passed to the National Trust.

There were two workings of the mine, the low and high, and as of 2015 the mill of the mine still stood. The building is a Scheduled ancient monument and the mine is a site of special scientific interest. The buildings can now be visited by appointment through the national trust.

As well as an aerial ropeway for transporting ore to the mill built in the late 1930s the mine also operated a small narrow gauge railway in the mine, utilising diesel and battery powered locomotives, one of which (Wingrove & Rogers Battery loco) is now at the Springfield Agricultural Railway, three 2 ft gauge wagons from the mine are to be found at the Moseley museum in Redruth Cornwall.
