In reply to Purely:
We went on 22nd May on a cloudy windy day, not too cold. The rocky bit at the start with the chains was clear of snow but greasy and slippery, naturally enough. As we went higher the snow patches got bigger until they were "un-dodgeable". Walking over them was perfectly OK in Vibram type soles - a soft four inches on neve beneath.
We didn't make it to the top - a bit of a problem with lack of map and compass! But on the way down we did, with much difficulty, find the infamous Kjeragbolten, and, though it involved glissading down a soft snow slope to get to it, and the traverse out was on cold greasy granite in thick mist, it just had to be stood on! I still get sweaty palms thinking about it. Unfortunately in the mist the photo is not as impressive as it should be.
