Meanwhile back in the cave..This was obviously a pre-dug cave, the floor was a couple of feet deep in small rubble, which I had a scrape around in and found a few pink fluorite crystals! A bit rough but pink and octahedral to a cm or two, mostly broken. In the back of the 4m deep cave there was a mossy crack just big enough to get your arm in. My headtorch revealed shiny faces, at full arm stretch. I could see the big smoky; it looked as if previous visitors had seen it too as it had a few bruises where someone had tried to dislodge it by jabbing an ice-axe at it. I managed to lever it out with mine, also utilising the lumphammer. I found several loose smaller smokies in the crack by feeling around, and getting cut in the process. Some of them are nice little floaters.
After a couple of hour I had to go, back on route up the arete to the top. It was very exposed and I had to use a ’back-rope’ kind of technique to protect myself; this was a first for me.
