This might have been 1992, but it was on the Ben. I think this is part way up No.4 Gully. The weather got worse till we were swimming through a near vertical wall of poweder. Foolishly we hadn't roped up on the easier ground and failed 20 yards short of the cornice. We had to cut a belay, rope up and cme back down. I still think we were lucky to get off the hill alive. To make matters worse I was using a collection of Dad's old 70's equipment. A walking axe and a short ice hammer.
