A famous rescue involving an ice axe took place during the Third American Karakoram Expedition to K2 in 1953. One of the climbers, Art Gilkey, was incapacitated by thrombophlebitis. The other climbers attempted to rescue him by lowering him down the mountain by rope, wrapped in a sleeping bag. While crossing a steep ice sheet, a slip caused Gilkey and five other climbers to begin falling down a steep slope. Climber Pete Schoening wedged his ice axe alongside a boulder, and managed to belay the roped climbers, saving their lives. (Gilkey, however, later in the same descent was swept away by an avalanche. Remains of his lost corpse were discovered in 1993.) Schoening's ice axe is now on display at the Bradford Washburn American Mountaineering Museum in Golden, Colorado.
