Alpine style
In 1957, Marcus Schmuck and Fritz Wintersteller made a flash first ascent of Skil Brum, in pure Alpine style. Starting from base camp of Broad Peak at 4,950 metres, they camped at 6,060 metres, made the summit the next day, then camped again at 6,060 metres, and then returned to base camp the next morning. The whole ascent, from base camp to base camp was done in 53 hours, a startlingly short time for a major Himalayan ascent in that era.
