Mount Owen, First Ski Descent. One more of the major Teton summits has been descended on skis, this time Mount Owen by Bill Briggs and Rob McClure on June 21. Putting on skis on the east ridge about 150 feet below the summit, they descended to the East Prong Col and from there down the remaining part of the northeast snowfields. A rope and belay were used on the 60-foot pitch during this section. The snow finally gave out about 500 feet above Cascade Creek, about three hours and 5000 feet after they left the summit.
