Gedling Colliery, in the Nottinghamshire coalfield, closed in 1991 after nearly a hundred years of activity. Rose Ferraby visits the site of the old pit tip, which has been converted into a country park, where she meets a local historian and a former mine worker as well as members of the Friends of Gedling Country Park. Down in the valley Rose visits the slurry lagoon, where waste water from washing the coal was piped out. The former industrial waste site has been converted into a thriving nature reserve with the help of the Gedling Conservation Trust
