Upper West Rib Variation

The Upper West Rib provides for a fantastic adventure on a classic line while still providing you with many of the aesthetics found on the West Buttress. On this climb, out team will ascent the standard West Buttress route up to Camp III at 14,200 feet. From there, we will climb up the West Rib Cut-Off to join the upper Rib.

After arriving at Camp III, most teams will make an acclimatization climb up to the 17,200-foot West Buttress camp. There they will leave a cache set-up for their descent a few days later.

After waiting for an appropriate weather window at Camp III, the team will work its way up the Cut-Off to join the ridge crest at 15,700 feet. Once the crest is reached, the climbing is absolutely fantastic. The team will climb a steep and sustained couloir to a protected camp at 16,400 feet.

On summit day, we will climb a six-hundred foot steep and windy couloir with sections of sixty-degree terrain to a flat spot at the base of the last crux. From here the team has two options, a traverse across the top of the infamous Orient Express couloir or an ascent up another steep couloir to the east. Both options top out on the “Football Field,” a flatish spot below the final summit ridge. From here, the route once again joins the West Buttress to the mountain’s summit at 20,320 feet.

Our descent will take us back down the West Buttress route to the camp that we prepped on our acclimatization ascent at 17,200 feet. From there, we will make our way down the West Buttress and back to Base Camp.

Advantages of Climbing the Upper West Rib

1. Climbing the Upper West Rib allows for a lighter ascent. If you climb the complete route, you must carry multiple days worth of food and fuel on your back. If you only climb the Upper Rib, the ascent to 14,200 feet will be sled assisted.

2. After climbing all the way up to Camp III at 14,200 feet, it can be demoralizing to descend all the way back down to the Northeast Fork of the Kahiltna Glacier to start your “real” ascent.

3. Though this is an incredibly physical climb, it is ultimately an easier ascent than the Complete West Rib.

4. An ascent of the Upper West Rib avoids the complexity and the objective danger that complete Rib climbers face in the Northeast Fork of the Kahiltna Glacier.

As in other parts of the world, AAI expeditions in Alaska are run with small groups of climbers who have carefully prepared for their objective. The Institute takes a team approach to its climbs, and expedition members are expected to take responsibility for themselves and a share of responsibility for the overall operation of the expedition. We do not accept climbers who are under experienced and who need to be “hauled” up and down the mountain. Trying to push ill-prepared climbers up the peak is what keeps so many guided and unguided groups from succeeding on Denali.

The Institute gives its climbers careful and detailed counsel in their preparations for climbing objectives and, when appropriate, has them first achieve intermediate goals. Climbs on Denali obviously involve many factors that we cannot control, among them temperature, wind, snowfall, and changeable climbing conditions. The key to success therefore lies in doing an excellent job on those areas in which a climber has some control: skill in dealing with cold conditions, skill in climbing at an appropriate technical level, and personal conditioning. To develop these abilities and then to combine them with a carefully designed and guided itinerary is the most direct line to safety and success.

AAI expeditions enjoy a rate of safety and success rarely matched by other teams. With well-prepared climbers, we do not have to rely on perfect conditions in order to move. Able to remain poised high on the mountain in poor conditions, our teams often make successful summit bids in small windows of good weather when other teams are out of position. AAI doesn’t pretend to guarantee good health, good weather, or success on these expeditions, but we are committed to building strong teams and creating high potential for safe and successful climbs. The average individual success rate on Denali is 54% overall and 59% in guided groups other than AAI. The Institute’s success rate is 70% for individuals and 75% for expeditions.

AAI has the highest level of commitment to environmental protection and restoration, and on all expeditions and instructional programs we teach and follow Leave No Trace ethics and practices for travel, camping, and climbing. The Institute has been a leader in the conscientious use of wilderness environments, including both remote and popular areas of Denali and the Alaska Range. Each year the National Park Service presents “Denali Pro” awards to individuals who have made major contributions to protecting the mountain. Over twenty AAI guides and climbers have had the honor of receiving this highest Denali National Park and Preserve award since its inception.

With regard to expedition processes, we make five to seven camps as we climb alpine style, moving all camps higher as we go and leaving none established above or below. It is not uncommon for temperatures high on the mountain to fall as low as -30F, but at lower elevations daytime temperatures on the glacier can reach as high as 70F, so there we sometimes sleep in the day and ferry loads at night when temperatures are between 0F and 15F. The night’s cold improves conditions under foot, and we still have adequate light because of the extreme northern latitude. Double carries are done during the first part of the expedition to ease the work and to help with acclimatization.

All expeditions begin with a meeting and orientation in Anchorage on Day 0. We spend one night there, then travel by van the next morning to the small town of Talkeetna. There we repack our equipment, meet our ski plane pilots, and as soon as possible, make the beautiful flight to the Kahiltna Glacier at 7300 feet. Soon after our arrival and a review of glacier travel procedures, we begin moving to our first camp.
