Moorland Caver (2003)
Small hole, completely choked with sheep carcasses, noted by Dr. Paul Fitton in 1949. The hole had been known to Duncombe Park keepers for a number of years and was used by local farmers for dumping carcasses (a traditional use for windypits and one that is still on going).
Various, unsuccessful, attempts have been made to locate Greencliff Hag (most recently by the current author in 1996) and it must be assumed that it is truly one of the lost windypits of Ryedale.
