The same view of Stanley Ferry Flash, near Wakefield, taken by Richard Brook on Sunday, 9 September, 1973 (above), and on Friday, 24 January, 1986 (below). The colliery spoil heap in the background, from one of the Stanley Collieries, perhaps Stanley Deep Drop, has grown, or at least been reshaped in the intervening years.
Part of the spoil heap area became Stanley Marsh Nature Reserve.
Common Reed, Phragmites, has colonised the area, although some reedmace remains. The rough grasses, greater willowherb and water plantain seem to have been drowned out, so I wonder if the whole site subsided, or whether water levels stayed about the same but the reed out-competed the other plants.
