Denali West Rib

Denali’s West Rib Expedition

A Climber’s Route

The Chicken Couloir

An aesthetic line sweeping up alongside the massive South Face of Denali, the West Rib is a challenging route for climbers with good technical experience, wishing to push themselves on what definitely qualifies as a “Big Route”.   Steeper, more exposed, more committing, and more serious than its neighbor, the West Buttress, the Rib is all about the climbing.  Complex glacier travel is required to access the base of the route, which quickly rears back to provide 50 -60 degree snow and ice climbing up the famed “Chicken Couloir” which affords access to the ridge and the rest of the climbing challenges ahead.

Since its first ascent in 1959, the West Rib has continued to provide beautiful alpine climbing in a spectacular setting.  Its rich history and moderately technical terrain still attracts the best climbers as they hone their skills.  The West Rib feels more remote than the neighboring West Buttress, which in combination with the inherent technical challenges gives the route it’s mystique and allure for climber’s looking for a different way up North America’s most sought after summit.

Alpine or Expedition Style?

There are generally two ways to attempt the Rib. One is to hike out of base camp will all your kit and climb the route expedition style, ferrying loads between camps, while you acclimatize on the route. Another style involves ascending the West Buttress route to gain acclimatization and to perhaps put a cache in at the high camp on the Rib. The team then descends back to the North East Fork of the Kahiltna at about 7,800 feet to access the route and climb it in alpine style. There are pros and cons to each method, and conditions of the route may ultimately dictate which style we pursue. The outlined itinerary reflects an alpine style attempt.

Permit Note

SJMG runs this trip in conjunction with our friends at Mountain Trip; an authorized Denali concessionaire.

1Before Your Expedition

The Denali West Rib Expedition is a serious undertaking and it is essential that you prepare thoroughly both mentally and physically.  In addition, the West Rib Expedition requires a higher level of technical skill so previous steep alpine climbing and/or ice climbing experience is required.  Previous completion of our Denali Prep Course, and other high altitude expeditions such as Ecuador’s Volcanoes is suggested prior to enrolling in this expedition.  Our Ice Climbing Courses also represent an excellent investment for the technical skills you need to have for this program.

For the West Rib Expedition you should be ready for:

  • 18 – 24 days on a glaciated high-altitude mountain
  • Carrying a pack loaded with food and gear up to 65 lbs.
  • Fickle weather, cold temperatures, warm temperatures, delays, other factors beyond our control

2Follow Up Climbs

I hope that I might be able to get out to Ouray again before ice season ends.  If so, I’ll definitely get in touch with you.  Working with the local experts really makes a difference.  Thanks again for everything! – N. Subashki. 2011 Private Program
