Full Trip Report
Spouse Wall is sloping rock face located on the lower flank of Mt. Garfield in the Middle Fork Snoqualmie River Valley northeast of North Bend. It can be reached from the Garfield Ledges Trailhead parking lot by a ¾-mile hike on a combination of formal trail and rough climber’s path. The rock consists of a solid, grippy, well-textured, volcanic material—probably a lightly metamorphosed andesite.
I had never heard of Spouse Wall until my friend Blaine invited me on a visit to the crag. According to Mountain Project, four multi-pitch sport routes were established here between 2021 and 2024. What caught our interest was two adjacent five-pitch sport routes named after a fungus and mold: Fusarium and Aspergillus, both rated at Class 5.8. Mike and Yoko joined us for an exploratory trip.
The Approach
Starting at the Garfield Ledges Trailhead alongside Middle Fork Snoqualmie River Road on a warm Tuesday morning, we hiked up the nicely graded trail. According to Washington Trails Association, this trail is relatively new, having been completed in 2019. It winds upward through pleasant second-growth forest with a lush understory of ferns and moss.
.
.
About 15 minutes of hiking took us past two minor viewpoints and up several sets of wooden stairs. Approximately 100 yards beyond the second viewpoint, the trail makes a sharp switchback to the left (0.56 miles + 400 feet from TH). This is where the Spouse Wall approach path branches off from the main trail. Look for a blue diamond on a tree, and a faint path angling downhill.
.
The approach path makes a descending traverse through sparse forest for 100 vertical feet, then climbs steeply for 150 vertical feet. It is well-trodden and easy to follow, with only a few downed logs.
.
After a final short traverse, we emerged from the forest and arrived at the edge of a 45-degree rock slope (0.75 miles + 550 feet from TH). This is the base of Spouse Wall. The Aspergillus and Fusarium routes begin on a sloping ledge about 10 and 15 yards, respectively, beyond the forest.
.
The Climbs
We all geared up at the base and then divided into two separate rope teams. Blaine and Mike headed up Aspergillus, while Yoko and I headed up Fusarium. The first two pitches of both routes involve straightforward (5.4 to 5.5) slab climbing on lichen-covered rock, with scattered ledges of dirt, grass, and moss. To me, it felt a bit like an alpine climb! All pitches are well-protected with ample bolts and end at two-bolt belay anchors.
.
Pitch 2 of Aspergillus ends at a belay anchor located near the left edge of a grassy slope below a steep face. Pitch 2 of Fusarium arrives farther to the right on this same grassy slope at a two-bolt rappel anchor. Both routes share a belay anchor, so it is necessary to traverse leftward across the grassy slope to reach the anchor at Aspergillus. However, to avoid congestion at the belay anchor, Yoko and I chose to belay from the Fusarium rappel anchor and then begin Pitch 3 with the slope traverse. This created some rope drag but worked well otherwise.
.
Pitch 3 of each route gets a little steeper and more difficult (5.6 to 5.7), but the rock is cleaner and the holds are solid. In fact, the rock quality is surprisingly good, with a gritty texture and a combination of chiseled and hueco-type handholds. Overall, Aspergillus is a bit more pure through here, whereas Fusarium maintains more of an “alpine” ambiance.
.
Things get more interesting on Pitches 4 and 5 of each route. On Fusarium, these two pitches involve some tricky face moves and delicate friction climbing; although they are rated as high as 5.8, I would say that they felt more like 5.8- or 5.7+. The final two pitches of Aspergillus are also rated at 5.8, but Mike and Blaine (and many other climbers) reported that Pitch 4 felt like 5.8+ or 5.9. We would describe the bolt spacing on all of these pitches as “adequate” but not “generous.”
.
.
Pitch 5 of each route ends at a two-bolt belay/rappel anchor a few yards below the edge of the forest. From here, you get a nice view of the Middle Fork Valley stretching out to the southwest.
The Descent
Upon topping out, climbers have two descent options: rappelling back down or walking off the top. Each option has pros and cons; both are reasonable but neither is ideal. Yoko and I elected to rappel down, while Blaine and Mike elected to walk off. Surprisingly, we all arrived back at the base of Spouse Wall at the same time. Here is what our group experienced and what I discovered on a subsequent visit.
The Rappels: Our descent got off to a bad start because I mistakenly thought that Yoko and I could combine Pitches 5 and 4 into a single long rappel. Our 70-meter rope did not reach the Pitch 3 anchor on Fusarium, so we had to do a short down-climb to reach the Pitch 3 anchor on Aspergillus. From there, we made a long rappel down to the grassy slope, then walked over to the Pitch 2 anchor on Fusarium. Two more rappels got us down to the base ledge. My take-aways from this experience are as follows:
- Don’t try rappelling down either route unless you have a 70-meter (or longer) rope.
- Don’t try to combine pitches; just do five pitch-by-pitch rappels.
.
The Walk-Off: Blaine and Mike described their walk-off as moderately exposed, but they had no navigation problems. After scoping out the walk-off option myself the next day, I discovered that there are two different exit paths—a high path and a low path. Here is a summary of the walk-off routes:
- After topping out on either route, look for a cordelette anchor tied around a large tree. The exit path begins here.
- Head upward to the left through the sparse forest. The path is vague but continuous, so keep a sharp eye.
- After a few dozen yards, you will come to an indistinct junction. From here, the right fork heads uphill, and the left fork heads downhill.
- The right fork angles steeply uphill for about 50 vertical feet, crosses over a hump, and then descends steeply for 200 feet to Garfield Ledge Viewpoint.
- The left fork makes a slightly descending traverse across the top of the cliff and arrives at Garfield Ledge Viewpoint in about 100 yards. There are a couple short Class 3 down-climbs along the way.
- After arriving at Garfield Ledge Viewpoint, hike 0.3 miles down the main trail to reach the previously described junction with the approach path.

Equipment Comments
Both of our teams used single 70-meter ropes on the two routes. Although a 50- or 60-meter rope would be adequate for either ascent, a 70-meter rope is needed if you intend to rappel back down; a 60-meter (or shorter) rope would not be long enough for rappelling either route.
For protection, we used about ten quickdraws, as well as one extended sling to reduce rope drag on the traversing portion of Pitch 3.
Yoko, Blaine, and Mike wore conventional rock shoes on the climb, whereas I wore La Sportiva TX Guide approach shoes (reviewed here). In the end, we each found that our footwear provided adequate friction on the gritty meta-volcanic rock.
