A large spoil heap associated with the Yorkshire Main Colliery at New Edlington. The pit shaft was sunk in 1909 and the spoil heap presumably started accumulating at about this time. Prior to the spoil heap the area was agricultural. It was probably enclosed by parliamentary award in the mid-18th century. The 1st edition OS map of 1854 also shows large areas of woodland within the fields. Legibility of the former landscape is invisible
