   A cave fragment exposed by the road works during 2002. Site 2996 is below the road.

   An originally wide, but now small entrance over concrete to a 3 - 4m high and wide passage that descends over boulders to where a greasy calcite slope ascends straight ahead to a choke with a draught. On the left near the base of the slope is a small hole that draughts - although this couldn't be found on visits in the summer 2011 and January 2018. Down to the left, various routes around boulders combine to reveal segments of passage that choke as they approach the surface at the road - see survey and video.
   In 2008, a small route on the right of the entrance passage (with the strongest draught in the cave) was pushed for about 10m. At the start this is clean washed and about 50cm wide by 80cm high for about 3.5 m dipping down steeply. At the end a boulder in the floor has to be crossed. To the right, there is a step into a parallel rift where the main draught seems to come from. This is about 25 cm wide and runs for several metres in both directions before closing down. You can see up several metres here and it may be possible to get to this higher level by climbing up back in the main passage. Back at the boulder the small passage continues for approx 2 to 3m before closing down to less than 20cm wide.
