The Blueberry route is a popular Darrington classic that has more feel of an alpine rock route than a crag climb. It is the easiest route up spectacular Exfolation Dome, the west face of which has been nicknamed “Blueberry Hill” for the wild blueberry bushes on many ledges. The alpine character applies to the climbing, which has sections of clean crack and corners interspersed with blocky scrambling and occasional bush pulling (thankfully scrappy cedars, not blueberries).

Blueberry Buttress is a compelling feature splitting the West Face of Exfolation Dome. Although not especially technical, this route is physically demanding with the Granite Sidewalk approach and deproach providing an added challenge physically, and for many, mentally. Do your homework, pack lots of food/water and headlamps....and your camera of course.

The well-traveled 7-pitch version attains Blueberry Terrace, a broad ledge around 2/3 of the way to the summit. From there, you can continue to the summit via scruffier climbing, or get started on the tricky rappel descent. The route-finding is fairly straight-forward and adds to the adventure, so is not described here in detail. The basics:

The Start: Above a large white snag find the obvious fist crack leading to a cedar bush (see photo). Continue toward a prominent right-facing corner on the buttress crest.

The Right-leaning Corner: Cimb the corner (slabby to right, overhanging on left), passing semi-wedged flakes and two bolts (5.8+). Make an airy step leftward (5.8+) out of the corner back onto the buttress.

To Terrace: Several more pitches of scenic crack and block climbing on the broad crest to Blueberry Terrace.

Terrace to Summit (optional, but definitely worth a visit!) : Walk left to the far end of the Terrace (~100 yds beyond turnoff shown in Smoot's Falcon guide). From there, scramble up and leftward until you see a bolt. Two short pitches (5.8 max) lead up and left until you can drop slightly left to unrope and walk to the summit.

For a more detailed pitch-by-pitch description, consult Weekend Rock: Washington by Whitelaw.

Descent is by double-rope rappels, and DOES NOT follow the climbing route. From Blueberry Terrace, either: 1. Rappel (skier's) left off slinged trees to the West Slabs and bolt anchors of the Westward Ho route, or 2. Find the top of the Dark Rhythm route which is several hundred feet (skier's) right of where Blueberry Buttress reaches the Terrace. Although Dark Rhythm has all bolted anchors, the line wanders a bit and finding anchors while descending may be tricky. Westward Ho is a more straightforward line and clearly visible from the Buttress route on the way up.


The approach follows the Granite Sidewalk, a broad slabby ramp described well in the writeup for neighboring route Dark Rhythm. The Granite Sidewalk is fairly steep and long and you would not want to tumble or even contemplate such a grisly fate. Many visitors will appreciate sticky approach shoes or even comfy rock shoes for this approach. It is both direct and memorable, though!


Standard trad rack. Bring long slings (24-48") for tying off trees and reducing rope drag. Approach shoes or loose climbing shoes desirable for the approach


Not far from Seattle, but feels really remote. The birch forest cathedral you drive through to get there is special - in the meanwhile the car sides and undersides are being buffed by green grass, green leaves and (mostly) green branches.

You could park immediately *before* the first wash or immediately after the second. Hike up the second wash, the buttress and approach will become obvious within 5 to 10 minutes. The buttress is *not* visible initially. This is emphatically the right way to go (insert description of a couple of hours spent scouting various gullies following the "start up the gully at the end of the road" approach)

When you get cliffed out, look for a small bent pine on climbers left that allows you to bypass the cliffage and get on to the Granite Sidewalk proper. The Granite Sidewalk is an amazing feature - a long tongue of low angle slab. Sticky rubber is nice.

P3 ("Right Leaning Corner") is an awesome pitch. It is the clean corner on the climbers left, not the mungy corner right above the belay (insert near epic off route adventure here). Early in the day (before the sun hits the buttress), it is hard to see the second bolt and the off route bolts from the belay. Also, the "airy traverse left" is quite a bit further up the corner.

We broke up the last pitch in two (1) trend up and somewhat right into a left facing corner with old tree (and tat?) and (2) more or less straight up to run out but low angle slabs. This brought it up to a total of seven pitches.

In general, the pitches are long and would be difficult to combine.

Rapped off at the (climbers) right edge of Blueberry terrace towards the Westward Ho route. One rap off a tree+fixed-tat and rest of bolts/rap-ring on clean slabs. Last rap to base of route off tree+fixed-tat. All two rope (with 60m ropes) raps except the last one.

At least in a few places you are climbing a slab next to an offwidth - would be somewhat runout without a big (#5 or #6) cam. But manageable - it is quite a ways to hike those big boys up there. We did it with doubles to #3 and found it to be ok. Jul 15, 2015

To rap off the summit, look for two bolts on the south-facing side (rap #1). A double rope rap on 60m's will get you to chains that are difficult to see (rap #2). The next station is fairly straight down (rap #3). The chains after this are climber's right -- do not go left and get stuck in the trees (rap #4). It's clean slab raps from there on out.

Crux dihedral is sustained but fair for the grade, exiting the dihedral is a blast, a few modest run outs but nothing too terrible or unexpected, fun mix of slab and crack moves.
The crux dihedral contains many loose, hollow sounding blocks with the potential to significantly alter your belayer's body, and the following pitch mainly climbs the fractures separating detached, hollow sounding sections of slab (might a fall on a cam send the entire pitch tumbling down?!?).

Interesting Dougie, folks have been climbing around those flakes for years because they looked pretty well wedged in. But a long-time local just reported that the flakes in the corner - and some others higher up - are now a LOT more loose than they've been in the past.

So best for everyone to AVOID this route for now and hope that Ma Nature does some housekeeping up there this winter! Oct 6, 2017
Curt, Dougie, or anyone else that may know, Did mother nature take care of the "scary flakes" on pitch three? I was looking to do BB this weekend! May 24, 2018

The last report (spring 2018) said the loose flakes are still there. And if mobilized they would presumably tumble down the Granite Sidewalk. Up to you, but I'd be inclined to do Safe Sex or something at 3 O Clock Rock instead. May 24, 2018

APPROACH INFO, INCLUDING GPX TRACKS: hiking.andrewbares.net/hike…

We tried this on May 13th, 2018. Got up most of the 3rd pitch where the first of the flakes in the corner are. There's indeed one flake that's being held together by a sling (the rock must have broken after the sling was placed around it), and I wouldn't be surprised if there's more.

We had to bail since we started too late. We considered going back last weekend, but decided against it since it sounds too dangerous and not worth it. Sounds like this area is constantly losing rocks.

But if anyone wants to try it, we collected a bunch of approach info, including GPS tracks, linked above. The approach is really great if you find the correct trailhead. Great trail through the forest, and then up the Granite Sidewalk.

Note that as of May 13, 2018, there's a fallen tree blocking the road probably about a mile before the trailhead. With a lifted 4WD 4Runner, I was able to drive over it, but anything lesser wouldn't be able to (yes, even Subarus wouldn't be able to). It's probably 1.5 feet in diameter. I was going to saw it next time we came through, but now we decided not to go back. May 29, 2018
