   One of three strongly draughting holes to the northeast of site 3300 and the Deep Rifts Passage in Torca la Vaca. The others are site 3470 and 3471.
A sandy-floored tube, about 30cm diameter on the side of a large shakehole in the edge of trees. A very strong draught on a cool day - well worth digging beyond the 5m or so already excavated.
   In April 2023, it was found to be "draughting nicely". Site 5350 is 10m to the north.
