Site of former colliery which was first established on this site in 1890 (Taylor 2001:79). This part of the site (see also HSY 2716) was outside the historic boundaries of the woodland in enclosed land (probably meadows) in the floodplain of the Blackburn Brook. Mine was the property of N.C. Thorncliffe Collieries Ltd, part of the Newton, Chambers and Co. Ltd. Complex of extractive and related industries based in Chapeltown / High Green. Fragmentary legibility of extractive activities despite apparent levelling.
