Moorland Caver (2003)
Examined by Raymond Hayes in 1943: “I was shown a peculiar hole in a field at Swinsty Farm 1 mile NW of Pickering. It was a circular pit about 12 or 15 feet wide and 10 feet deep. Passages leading off were blocked by earth. I was told it was an old watercourse and someone had explored one of the three passages but had to return because of foul air. The district is on rising limestone ground and to the east are extensive quarries which we examined for caves and found none.”
