In the 18th and 19th centuries Hebden Gill (or Ghyll) was a busy lead-mining area. Bolton Haw Crags are high on the eastern side of the Gill. The two piles of stones were built by the miners in their breaks. They are called "stone men". They are also to be found in other mining areas, e.g. on Abbotside Common above Hardraw in Wensleydale.
