Length 10m Depth 15m
Area position

   The grid reference may be wrong and the site could be closer to sites 4079 and 4080, explored on the same day.
   The entrance is a possible stream sink at the base of a small valley. A crawl under boulders leads back up under the valley to a short climb down into a small chamber. Another climb down over boulders ends at a very tight pitch head. The rift was rigged to a jammed block but entry to the pitch (estimated to be 10m deep) was too narrow, although it widens out below.
   (There should be a picture of the entrance.)
