This is a north-easterly view over the Don valley and part of Conisbrough, South Yorkshire, near Doncaster. The photo was taken from the disused quarries in the Lower Magnesian Limestone (Edlington Formation) at North Cliff, Conisbrough, sometimes known as 'Conisbrough Crags', sometimes as 'Denaby Crags'. The buff-coloured embankment across the valley is 'Cadeby Crags' - the scarp slope of the Lower Magnesian Limestone. The site of the former Cadeby colliery is just in front of Cadeby Crags. Cadeby village is on the distant skyline at (0.2, 0.6). The disused buildings of the Earth Centre are at the extreme left (0.05, 0.5).
