Document with SMR backup file (HSY 4172) relates to plans to reuse former Lime quarry in this area as a landfill site. Historic mapping from 1851 -1948 shows lime extraction sites along the "Warmsworth Cliff or Levitt Hagg" linked to lime kilns and wharfage by the River Don. This cliff edge moves progressively towards the full extent of this polygon by 1966. Since 1966 'Dolomite' extraction has continued to the south east of this area.
