The 6ft high entrance is normally semi-flooded by a pond. The passage slopes downwards but ends at a fall after 55 yards, at this point the height is 4ft 6 inches with 3ft of water. The fall has been bypassed and water pumped out to reveal that the passage continued for a further 100ft. It was not explored beyond this point since it still sloped downward and the air space was too small. A shaft marked on the map has not been found.
