Steeply sloping common land with a long history of surface mineral extraction and recreational use. Possibly formally enclosed as a part of the Conisborough and Clifton Enclosure award of 1858 no enclosure boundaries were erected across the majority of the common which has always been depicted as rough ground by the OS. Now designated as a SSSI on account of its limestone flora. Features include the remains of a cable incline associated with former lime kilns (HSY 4584).
