The West Buttress route on Denali was pioneered in 1951 by Dr. Bradford Washburn. The climb is a steady and gradual ascent over a period of days, and we emphasize proper acclimatization for our team members. With no rock or vertical ice climbing, the route is not considered a highly technical climb. However, the physical environment of Denali presents much of the climbing challenge: miles of heavily glaciated terrain, extremes of temperatures and weather, and climbing and living at altitude. In addition to extensive glacier travel on the lower mountain, the climbing is considerably steeper above 15,000' (35° to 45°+). Some slopes have fixed rope in place to climb with the belay of a mechanical ascender. An ascent of the West Buttress of Denali with RMI is truly a major expedition and unforgettable climbing experience!
The remote and inhospitable landscape of Denali's slopes necessitate that all the finer points of an expedition are addressed, and our years of leading mountain adventures give us the experience and knowledge to create the best possible trips; we work hard to live up to our reputation as an industry leader. Our preparation before departure helps you with the trip logistics - expedition planning, travel plans, mountain flights with K2 Aviation - so that you can focus on preparing for the climb. RMI does not have a pre-determined ending date for our expeditions, giving us the flexibility to take into account considerations such as weather, route conditions, acclimatization, and the strength of the climbing team while on the mountain. This flexibility allows us to move higher when the weather permits and climbers are ready, not just because of the need to adhere to a pre-determined schedule.
Our Denali expeditions are led by RMI’s foremost guides who bring years of climbing experience not only in Alaska but on mountains all over the world, from the Andes to the Antarctic to the Himalayas. With over 35 years of accumulated knowledge guiding Denali, our guides are second to none. Our guides closely monitor climbers’ performance and acclimatization throughout the team’s ascent and will make day-to-day variations to better your chances of reaching the summit. As you reach higher elevations and test the limits of your experience, the value of an accomplished, highly trained RMI Guide held to our standards cannot be understated.

Our main goal today is to get the team ready to fly onto the mountain. After our breakfast meeting, the team attends a National Park Service presentation on expedition climbing and special considerations about Denali National Park & Preserve. Next, we focus on equipment, including an extensive personal gear check and recommendations for what to bring onto the mountain and how to pack for the flight to Base Camp. Finally, we organize the group food and equipment, putting the final touches on our packing for the flight. We enjoy a final meal in town before our expedition begins. Overnight in Talkeetna.
Day 3 - FLY TO KAHILTNA BASE CAMP • 7,300' | 2,225M
After breakfast we meet at K2 Aviation for the bush plane flight to Kahiltna Base Camp, weather permitting. The spectacular scenic flight takes approximately 45 minutes. Kahiltna Base Camp lies at 7,300' on the S.E. fork of the Kahiltna Glacier, approximately 20 miles distant and 13,000' below the South Peak of Denali, at 20,320'. At Base Camp we rig our sleds and review mountaineering skills needed for our climb.
THE EXPEDITION
There are many variables on a Denali expedition. While most expeditions average 18 days from Base Camp to Base Camp, we never place an ending date on our programs. We purposely build flexibility into our itinerary to take into account weather, route conditions, acclimatization, and the strength of the climbing team. This flexibility allows us to move higher when the weather permits and climbers are ready. Our experienced guides closely monitor climbers' performance and acclimatization throughout the team’s ascent and may make day-to-day variations in order to better our chances of reaching the summit.
We pack each expedition with twenty-two man-days of food. In the event of bad weather, this amount can be stretched several additional days. Furthermore, there are emergency food rations at Kahiltna Base Camp, in case weather prevents the group from flying off the glacier.
The following itinerary is meant to highlight the camps, route details, and a day-to-day outline while on the mountain. It does not take into account any sort of delays.
Day 4 - KAHILTNA BASE CAMP TO THE BASE OF SKI HILL • 7,800' | 2,377M
Leaving Kahiltna Base, we descend 400' down Heart Break Hill to the main Kahiltna Glacier, where we turn towards Denali and travel 5.5 miles up the gently rising glacial rolls. Our camp sits at the base of Ski Hill at 7,800'.
Day 5 - BASE OF SKI HILL CAMP TO 9,600' CAMP • 9,600' | 2,926M
Ski Hill is the first major elevation gain of the trip. In a series of rolls, the Kahiltna Glacier rises from our camp at the base of Ski Hill towards Kahiltna Pass at 10,000'. We leave camp, and climb up the glacier to our second camp at 9,600', just below Kahiltna Pass.
Day 6 - 9,600' CAMP TO 11K CAMP • 11,200' | 3,414M
