On the walk up to the bivvy, Deep and I wandered off-piste to try and find a flatter route to the bivvy, avoiding the choss-bowl just before the bivvy. And bugger me, we accidentally found a cave. To get there, turn left in the open bit just before the choss-bowl, and its up a little gully. I decided to introduce Chantalle and Deep to the delights of surface surveying. We went over there, and I placed a tag bolt (2006-08), while Deep took photos and then explored. The cave is a 13m long 45 degree inclined passage to a small chamber, where light can be seen coming through a too-tight hole at floor level. Two survey legs later, we went home.
