   An open hole in a field surrounded by a fence and trees. A slippy traverse and climb down or a p6 lands on a bouldery slope. At the bottom, an obstructing boulder has been snappered out of the way. A very loose passage leads down over boulders to a cross rift which is choked at the bottom. There may be a digging possibility towards the rift, but shoring would be needed.
    Some work in the summer and Christmas 2016 and August 2017 confirmed that any progress would require a long dig and possibly some shoring/stabilising.
