Historic maps from 1851 until 1930 show this area as containing small buildings adjacent to the present disused 'shaft' and linked by an 'inclined plane' to further 'coal pits' at Upper Haugh to the west-north-west. The 1891-1930 256 inch OS maps label the site 'New Deep'. Probably the site of one of the earlier 'Stubbin' collieries replaced by Earl Fitzwilliam on construction of 'New Stubbin Colliery' (HSY 3774) in 1915. Partial legibility of early deep coal mine. Line of inclined plane still partly visible.
