   A walk-in entrance in the scar at the back of the depression. Six metres in is an artificial wall with a hole through at the left hand side. Beyond, the passage splits at a stal column. To the right, the route steps up into a hands and knees crawl, lowering to a flat-out crawl after 6m. This goes a further 10m or so to where the way on lowers and is blocked by mud and stal.
   To the left, 6m of walking goes to a partially walled-up window into a chamber with a sloping floor. The right hand wall has old stream deposits under calcite. At the far side is a slope up then a tight spot and an excavated section up a slope. Here the passage is seen to continue and the draughting route was pushed in the summer, 2012. A boar cranium was discovered in this area.
    The route is low for about 5m and filled with roof debris. A drop down enters a small chamber with a further drop where the passage turns 90 degrees. The passage here is low and 20 - 30m long. Another excavated constriction enters more low, but slightly wider (1.5m) passage. The way ahead appears to be more of the same to what looks like another drop in the floor and a bend to the right. Approximately 60 - 80m were pushed but not surveyed.
