Site of Cliff Wheel (shown 1877 OS 25 inch Derbyshire), constructed by George and Thomas Hutton, Ridgeway and Mosborough Sicklesmiths in 1805 (info held in Mosborough parish file). Site still shown on the 1877 OS as a grinding wheel. Only the earthworks of the Dam are shown on the 1891 OS. Later within the site of Birley East Colliery in operation from 1907-1988. Used by the NCB as a training centre. Used as a Pumping Station from 1977 to 1988 (http://www.nmrs.co.uk/yorkshireminesb.htm -accessed 13 Dec 2005) Late twentieth century mapping shows a large spoil heap covering much of this area, cleared by 1999, currently regenerating as scrubland. Fragmentary legibility of coal mining history. Earlier mapping shows enclosed strip fields either side of the wooded steep sided valley of the Shire Brook (also a historic parish boundary).
