Early 21st century housing on the site of former spoil heaps of the Cortonwood Colliery. Taylor (2001, 118) dates Cortonwood back to the 1873 sinking of a shaft to the Barnsley seam. However a 'Cortwood' Colliery is depicted on this site on the 1855 6 inch OS mapping. The announcement of the closure of Cortonwood on March 1st 1984 (http://news.bbc.co.uk/onthisday/hi/dates/stories/march/12/newsid_2540000/2540175.stm) led directly to the 'Great Strike' led by the National Union of Mineworkers between 12th March 1984 and 3rd March 1985. The mine closed in 1985 with the loss of 800 jobs. No legibility of earlier landscapes. Pit head buildings cleared by 1989. This area formerly lay within the former open 'West Field' of 'Brampton Bierley' as surveyed for Parliamentary Enclosure by Wm. Bingley in 1816 (Sheffield Archives NBC 58).
