I thought I had climbed this, but looking now I can't see how I could have done. I did climb something which was equally terrifying, a elevated section of rock that had a chasm partially separating it from the main mountainside. Thick with cloud, I lost the path (or maybe it was never really there) tried to traverse round to descend via intended route south east but impossible so retraced route descending north before walking back along the valley to car.
