Part 2 of this three part Cascade climbing series will cover The West Ridge of Forbidden Peak.

Part 2: The West Ridge of Forbidden Peak

Part 1: Fisher Chimney’s, Mount Shuksan

Part 2: The West Ridge, Forbidden Peak

Part 3: Disappointment Cleaver, Mount Rainier

After our successful summit of Mount Shuksan via the Fisher Chimney’s we took a rest day and camped at Douglas Fir Campground. The next day we drove to the ranger station in Marblemount to collect our back-country permit and then took the scenic Cascade River Road to the trail-head.

The Route

The West Ridge of Forbidden Peak is one of the “Fifty Classic Climbs of North America” and is considered Grade II, YDS 5.6. After a half day approach into Boston Basin the route climbs a perennial snow field before ascending a moderate gully to one of the most spectacular ridge climbs you can imagine. Massive exposure with relatively good rock quality and a stunning summit make it easy to see why this route made the aforementioned list!

Weather

We went for the second half of July and were lucky to nail a 12 day stretch of excellent weather. June, July, and August can all offer great summer alpine climbing conditions with June being a bit colder and wetter and August opening up a bit more crevasses on the glaciers.

Day 1 GPS Details

The approach trail climbs about 3,300 feet in 3.75 miles and took us exactly three hours. We found some level tent sites at the “upper bivy” right at the toe of the snowfield that provided plenty of running water. A few brief showers came through and we were treated to some excellent “god rays” as the sun set and we turned in for an alpine start.

The next day we started out at about 4 AM.

Day 2 GPS Details

Easy climbing up through the snowfield brought us to the start of the gully that would allow access to the ridge. The “Heartstone” is a rock buttress directly above us in the photo that serves as a good landmark for finding the snow gully that is hidden from view. The route climbed up thinning snow just to the left of this feature. In the gully proper the snow climbing was straight forward until we hit a glide crack that required a big balance step to surmount. The snow ended about 200 feet from the ridge so we pitched out a few short 3rd-4th class pitches. This stretch was the only place on the ascent that had a decent amount of loose rock so care was needed.

We stashed our mountaineering boots, crampons, and ice axes and switched into approach shoes for the rest of the climb in the small col on the ridge. The exposure begins almost immediately with a airy step over a gap in the ridge with a chock-stone that perfectly frames the lower snow gully you just climbed up. You can see this spot clearly in the video I will link further below.

The climbing was enjoyable, the rock felt solid, the views were un-believe-able… For speed we mixed up our techniques between simul-climbing and short-pitching with only about 20 meters of rope between us. This made for easy communication and simplified rope management.

We made the summit in 7.5 hours after leaving our camp in Boston Basin having climbed 3.9 miles and over 2,500 feet in elevation. The small pointed summit of Forbidden is one of the most amazing places I have ever stood in the mountains. The terrain is so dramatic as you look back along the ridge you just traversed and see the thousand feet of air on each side.

Descent

After refueling we reversed direction and returned to the col to collect our snow gear. We then scrambled down to skiers right of the snow gully we had ascended and located the first rappel anchor in “Cat Scratch Gully”, an alternate 4th class ascent route to the snow gully. Five 30m rappels brought us to back to the snowfield where we enjoyed some decent boot glissading in the warming snow all the way back down to our camp.

We packed up camp and hiked back out to the trailhead in just under 2 hours.

Summary

I’ve had some time to reflect on this climb and I can say with certainty it will be one of the most memorable climbs of my life. I feel so fortunate to have not only had the opportunity to climb it but to do so with such great partners and friends and perfect weather and route conditions. I hope this trip report and guide might help you plan a trip to this incredible place someday!
