A track-side cave (GPS above) leads to another entrance in the field. There are two low chambers with a mud floor currently occupied by a badger. The field entrance has a GPS reading of 30T 454102 4795505; ETRS89: 30T 454000 4795296, but this appears to put the field entrance on the track. Length 15m?
