Korean Direct
AAC Publications Korean Direct The First Ascent Of Gasherbrum V Insignificant against the blinding white backdrop of Gasherbrum V’s south face, we stood like silhouettes atop a moraine, the wall before us in full view. The complex glacier leading up to the face reminded me of scaly dragon’s tail. We had spotted a snaking line that would lead us to the jagged bergschrund at the foot of the wall. Once on the face, we would have to keep left to avoid a menacing serac, then move right in the upper mixed section before finishing with a direct line to the top. Seong Nak-jong and I had never really considered a route on the south side of unclimbed Gasherbrum V until we were denied passage up the northeast face. We had started our first attempt on the 7,147- meter peak from Camp 1 on the South Gasherbrum Glacier, along the normal routes to Gasherbrums I and II. We trudged through thigh-deep snow to reach the northeast face, which was covered in loose ice and snow, and was nearly impossible to protect. Falling ice and spindrift poured down from above. We finally had no choice but to evacuate from our high point of 6,400 meters. This unsuccessful attempt quashed our desire to climb. As the leader of our small team, the quandaries of a second attempt weighed heavily on my mind. Not only were we physically weakened and our confidence shot, it was already mid-July and more snow was laying siege to the camps. We had been away from home for more than a month. -

fllie M®��1f�l]�r;r;m Published by Seattle, Washington..., 'December15, 1953 THE MOUNTAINEERS, INC. ITS OBJECT To explore and study the mountains, forests, and water cours es of the Northwest; to gather into permanent form the history and traditions of this region; to preserve by encouragement of protective legislation or otherwise, the natural beauty of North west America; to make expeditions into these regions in ful fillment of the above purposes ; to encourage a spirit of good fellowship among all lovers of out-door life. THE MOUNTAINEER LIBRARY The Club's library is one of the largest mountaineering col lections in the country. Books, periodicals, and pamphlets from many parts of the world are assembled for the interested reader. Mountaineering and skiing make up the largest part of the col lection, but travel, photography, nature study, and other allied subjects are well represented. After the period 1915 to 1926 in which The Mountaineers received books from the Bureau of Associate Mountaineering Clubs of North America, the Board of Trustees has continuously appropriated money for the main tenance and expansion of the library. The map collection is a valued source of information not only for planning trips and climbs, but for studying problems in other areas. NOTICE TO AUTHORS AND COMMUNICATORS Manuscripts offered for publication should be accurately typed on one side only of good, white, bond paper 81f2xll inches in size. Drawings or photographs that are intended for use as illustrations should be kept separate from the manuscript, not inserted in it, but should be transmitted at the same time. -

Observations show that glaciers around the world are in retreat and losing mass. Internationally coordinated for over a century, glacier monitoring activities provide an unprecedented dataset of glacier observations from ground, air and space. Glacier studies generally select specific parts of these datasets to obtain optimal assessments of the mass-balance data relating to the impact that glaciers exercise on global sea-level fluctuations or on regional runoff. -

Due to the committing nature of the route, its remote location, and its sustained steep angle, Liberty Ridge has the reputation of being the hardest and most-dangerous regularly climbed route on Mount Rainier.
