Black Rock The site of Fourth Meer Scrin Mine (subsequently incorporated into Cromford Moor Mine). Most of the structures have been removed during the reclamation and conversion into a picnic site, but the chimney on the left survives. The water tank on the right fed from a spring was also removed when the railway closed, although the spring and water supply still feed a stone trough erected at the same site. The view is looking east towards Black Rock. 20th Cent
