Spoil tip associated with the adjacent Markham Main colliery. The site is undergoing remediation and plans are in place to redevelop it as a community forest. Formerly the site was shown as the location of sand and gravel extraction. Prior to this, the site was agricultural. It comprised small strip fields consolidated from the furlongs of the medieval open field. The open field area is shown still marked as 'West Field' on the 1st edition OS map of 1854. Legibility of the former character is significant as all traces of the colliery have yet to be removed.
