[TR] Denali - Cassin Ridge (Alaska Grade V, 5.8, AI4, 8,000ft), Alpine Style* 06/09/2018

Recommended Posts

Trip: Denali - Cassin Ridge (Alaska Grade V, 5.8, AI4, 8,000ft), Alpine Style*

Trip Date: 06/09/2018


Between June 2 and June 11, Priti and I climbed the Cassin Ridge on the South Face of Denali approaching via the NE Fork of the Kahiltna Glacier (the “Valley of Death”), spending 6 days on route (including 1 rest/weather day at 17,700ft), summiting on June 9, and descending the West Buttress route.  The whole trip was 10 days 7 hours door-to-door from Seattle.

The Cassin Ridge is the second most popular route on Denali, with an average of 9 successful climbers each year, compared to an average of 584 successful climbers each year on the West Buttress route over the past decade.  We carried everything up and over, climbing Ground-Up, with 38lbs packs each at the start, no sleds, and moving camp as we climbed, without caches.

It was a Smash ’n’ Grab, meaning we decided to go at the last minute when we saw a good weather window.  We watched Denali weather every day since early May until there was about a week of good weather.  It took 24 hours from being at work on a Friday afternoon deciding to pull the trigger to being at Kahiltna Base Camp (including packing, Ranger orientation, flights, etc).  We climbed Rainier 3 times the month and a half before our trip (Gib Ledges, Kautz, and Liberty Ridge), sleeping in the summit crater the weekend before.  Still, we took Diamox while on Denali and had 2 weeks of food/fuel in case we felt altitude on route.  Luckily, we had no altitude issues, and were only bounded by our own fitness, weather, and desire to move only when the sun was on us.  Overall, weather was windless, clear, and sunny during the days with a few flurries at night.

It was an “old-school” style of climbing, slow and heavy, while most folks nowadays opt to acclimatize on the West Buttress and climb the Cassin Ridge starting from 14,000ft camp on the West Buttress, then climb light-and-fast via the Seattle ’72 ramp or the West Rib (Chicken Gully) in a few days — this was our plan for our attempt last year with Ilia Slobodov, but didn’t get the weather window.  Overall, a very successful trip, and we’re so excited to have pulled it off, after 3 years of dreaming of this route.

*Alpine Style:

The route was completed Alpine Style with the following exceptions:

-Snowshoes were cached at Camp 1 in case the lower Kahiltna Glacier was sketchy on the way back.  Didn’t really ever need snowshoes.  The NE Fork was boot-able.  There weren’t tracks going up the NE Fork, but it was wanded to the base of the West Rib.

-We clipped into the existing fixed lines on the West Buttress descent above 14k, but this was unnecessary since it was basically a staircase.  We didn’t clip into the existing pickets on the Autobahn above 17k.

Google Street View:

Apparently, nobody had done a 360 Photo Sphere Google Street View of the summit of Denali, so we obliged :)



-June 2: Arrived at Kahiltna Base Camp at 3:00PM and moved to “Safe Camp” in the NE Fork of the Kahiltna Glacier (“Valley of Death”).  We cached snowshoes at Camp 1 and took a right turn up the NE Fork.  This “Safe Camp” is the widest part of the NE fork, where you are least threatened by avalanches and serac-fall sweeping the entire valley floor.

-June 3: Hiked from "Safe Camp" halfway down the Valley of Death and climbed the Japanese Couloir and camped on Cassin Ledge with a sweeping view of Kahiltna Peaks and the entire NE Fork.

-June 4: Climbed the 5.8 crux, Cowboy Arete, and Hanging Glacier, camping at the Hanging Glacier Bergschrund at the Base of the First Rock Band

-June 5: Woke up to Colin Haley strolling by our bivy site on his 8hr7min speed ascent of the Cassin Ridge (he approached via the East Fork of the Kahiltna Glacier).  This was a total surprise and very inspiring see him up there!  We climbed the First Rock Band that day and bivied between the First and Second Rock Band just next to the rib.

-June 6: Climbed the Second Rock Band and found the crux to be the sustained "Hidden Rock Couloir" at the entrance, which is sustained mixed 70-80deg for about 50m.  At the end of the Second Rock Band, a Chilean Team of 2, plus Colin Haley, plus our team of 2 all took the wrong (harder) exit.  From the overhanging triangle, we all traversed right about 40ft then went straight up, finding difficulties to M4-M5.  We should have traversed right another 40ft or so to find the 5.6 slab pitches and the 5.6 dihedral as described in Super Topo.  This ended the technical difficulties of the route.  That night, we bivied at Mark Westman’s “excellent bivy site” at 17,700ft.  This turned out to be very hard to find and we spent several hours looking around for it.  It is way further up and right on the col than expected.

-June 7: Lots of snow!  So we decided to sleep all day, acclimatize and waiting out the weather.

-June 8: So much snow accumulated on the upper mountain the previous day that it took us over 12 hours to ascend the final 2,500ft to Kahiltna Horn.  We were knee to waist deep almost the entire day.  Mark Westman told us later that he was watching us all day through the high-powered scope from Kahiltna Base Camp and he could see the long trench we left in our wake.  Presumably, many day-tourists at Base Camp watched us in our embarrassing slog to the top.  This was by far the hardest day of the trip!  When we reached Kahiltna Horn at 10:30PM, we had no energy to go to the summit, so we slept on the “Football Field” at 20,000ft.  The night was beautiful, calm, and cold!

-June 9: Went back up to tag the summit, then descended 12,500ft to Camp 1.

-June 10: Got to Kahiltna Base Camp from Camp 1 at 10:00AM but it was overcast all day so TAT could not come and pick us up.

-June 11: TAT finally picked us up around noon, after we endured the most miserable and wettest night of the entire trip!

Nice job on a weather window and slogging it out.

BTW the two old guys with me on Sunset Ridge, we did the Cassin in 2000. Our group was called "Old and in the Way." We took 5 days on the route but had stellar weather the whole time.

Outstanding! Thank you for sharing this. Very nice style and preparation. You made it seem like a casual weekend outing in the Cascades. I'd love to do this route in a similar style. Very well done!

Really cool. As an average guy with a full time career with a hope of some day doing the cassin I really like the style you did it in. I hope you don’t mind if I ask a couple questions:

Did you split your packs into a lighter lead pack / heavier follower pack for the Crux pitches?

I see  you did some pre acclimitizing on rainier before going, but what have you the confidence you could acclimatize on Route?

How did you convince your boss you could take off for a week at a moments notice? (That’s a flippant but also kind of serious question....)

really cool!

The boss that pays you or the other one?

But who is the boss, really? :lmao:


Nope our packs were the same weight, both when leading and following. On the upper 2K foot wallow, one 1.5L water bottle move back and forth between leader and follower.

Last year we summited Denali, so we knew we dealt with 20K feet OK. We got the idea from the Smileys who had a similar schedule and felt the altitude but managed.

We asked our paying bosses, very nicely. :):)

Awesome trip report, Jeff! I was on the Kahiltna about the same time, trying (unsuccessfully) to solo Foraker.

Your route overlay of the West Rib and Cassin is informative but slightly wrong. That is "Kahiltna Notch" not Pass (Pass is between West Buttress and Mt Capps). And the top of the West Rib goes left of that rocky rib instead of to the right like you have it (going right leads you up to that huuuuuge cornice). I did the upper rib last year, aiming for Cassin next year.

Well done!
