 October Couloir Pursuits   

Alpine snow climbing is probably my favorite style of climbing in the mountains, so I've been anxiously awaiting next spring to be able to get back out into steep snow, especially on skis. However, after hearing about Colorado's somewhat elusive fall couloir season, I had my eye on conditions up high in hopes of sneaking in a fall climb. After the most recent snow storm, it seemed like northern aspects in the Sawatch range were promising. Lately, I've been partial to interesting 14er routes that also include centennial 13ers; after poking through peak condition report to see where the best snow might be, I settled on the north face of Missouri Mountain, with jaunts over to Iowa Peak and Emerald Peak.

I had skied the north face of Missouri last April and had a blast, so I was seriously considering a ski attempt this time around, but deemed the ski haul to be too long. I'm very glad to have left the skis at home; the shark fins would have made the descent very dangerous, if not impossible.

During last spring's ski descent, I triggered a thin wind slab/sluff on a ski cut (less than 2 inches deep) that slid on a bulletproof consolidated surface down most of the couloir. It wasn't anywhere near big enough to bury anyone, but still spooky nonetheless. Coupled with the recent avalanche on a similar aspect near Independence Pass, I knew that snowpack evaluation would be important, even in October.

Now that the exposition is out of the way, onto the climb:

I started driving out to the Missouri Gulch trailhead in the wee hours of the morning. The final dirt road was in washboard condition, but nothing that the alpine Prius couldn't handle. I started up the trail shortly after 5:30, making pretty decent time. Given that the clocks haven't changed yet, a very late sunrise was in store (after 7). As dawn started hitting the gulch, I was greeted by a welcome sight: the north face was holding a decent amount of snow.

Alpenglow on Missouri

I ascended 2 switchbacks on the Missouri side of the Missouri/Elkhead junction before heading straight up the steep talus field into the amphitheater at 12.8k.

In the amphitheater

This photo shows the 4 primary couloirs on the north face. I had initially been planning to ascend either main couloir or the C couloir (second from the right, and rightmost, respectively); however, walking through the snow in this talus field made it clear that the directly northern aspects were unpleasant loose powder. Additionally, the C couloir had a slope that seemed big enough to have a consequential slab. So, I opted to start up the leftmost real couloir in the photo, mostly due to its more western aspect (the slope at the base points right in the photo, not straight at the camera). I walked up to the base, donned crampons and a helmet, grabbed my axe, and started up.

My approximate route (taken on descent)

The more north-facing snow at the base ranged from fairly loose powder to just straight-up facet wading, making for slow progress. Climbing unconsolidated steep snow is a real sisyphus-esque task. As I reached the more northwest aspect, the snow turned to perhaps 8 inches of snow, on top of a thin sheet of ice and very consolidated snow, on top of rock slabs; though a bit less secure, this section was somewhat frontpoint-able, making for faster progress. The ice/snow layer also seemed like it would allow for an arrest if a slip were to have occurred.

Top of the NW aspect

The couloir arched right and started facing more north, meaning that the posthole madness resumed. I climbed for maybe 200-300 more feet (mostly postholing, but sometimes punching through to rocks).

22417_04
Exhausting progress

You may be raising an eyebrow at how the snowpack looks in that photo. Around this point, I noticed an abrupt shift in the snow: there was a bit more of a cohesive slab on top of the endless facet layer. The slab wasn't as thick as it looks in that photo, but I still wasn't a fan. So, I decided to switch to the rock spine to climber's right of the couloir. A few fun mixed moves perched on just a front point gave way to much easier rock terrain.

Eventually, the snow in the couloir started thinning out a little and appearing a little more reasonable and less consequential, so I decided to hop back in.

22417_06
Traversing back into the couloir

Right before the snow ended in the couloir, I noticed a VERY dense but thin (1-2 inches) slab in the top of the snowpack. It was so dense that I could yank off huge chunks of it. I exited back onto the spine and tossed a few rocks in to see if the little slab would slide; I couldn't get anything to move.

22417_07
Where I started pulling off chunks of slab (the snow ends just above this)

I traversed the rock spine, a short snow field, and one more rock spine before popping out on the summit ridge. A quick ridge walk led to a beautifully warm summit.

That concluded my first non-spring couloir climb. I found the snow surprisingly reasonable, and not too sketchy. However, I think the next big storm that rolls through may very well turn that face into an avalanche death trap.

Now, time to pack up the axe and crampons and head over to Iowa and Emerald.

Bonus photo of the Huron group

A straightforward, mostly dry ridge walk led to Iowa Peak (I believe either soft-ranked or unranked?).

Every once in a while, it's possible to find unbelievable silence in the mountains. Standing atop Iowa, on a warm and windless day, I had a few moments of that kind of silence. I watched a group stand on top of Emerald, talking to one another, and I could hear them chatting, despite being nearly a mile away. Wow, the mountains are neat. I started to head over to Emerald.

A trio descended the Emerald ridge

The ascend up Emerald includes some obnoxious talus-hopping, but it's short-lived.

A little while later, I topped out.

On Emerald, looking at Harvard and Columbia

While the actual climb of Emerald was nothing special, the surrounding area and peaks, coupled with its remoteness is quite neat.

Looking back towards Belford, I could tell that Elkhead Pass would be FAR. I descended Emerald's ridge, and then a steep grassy/snowy slope down into Missouri Basin (who names these places?), and got a better look at the slog over to Elkhead.

Emerald and the slope descent (I walked down near the snowfield on looker's left)

I thought that it might be possible to contour instead of descended to the trail low in the basin, so I gave it a go. It was possible, but the side-hilling was difficult, and probably not worth it compared to regain on the trail.

Once at Elkhead, I took a moment to hydrate and eat a Pop Tart, before starting down the gulch. The descent was relatively fast, but the vert and miles were starting to sink in.

The beauty of Missouri Gulch on the descent

There are 8 switchbacks on the steep slope on the way back to the trailhead. I know that because I was feeling over it and decided to count.

At long last, I maybe it back to the trailhead. I switched out of my climbing boots, and was greeted by some on the worst blisters of my life on my heal. They're not new boots or anything, but I haven't used them since the spring so maybe that need to be broken in again?

On the way home, I stopped in Leadville at City on a Hill for some amazing coffee and a burrito; that place seems to make an appearance on most of my trips to the Sawatch range.

Overall, this was an excellent day spent on some cool peaks!

Thanks for reading :)

Fall couloir season..

looks pretty much how I would expect, haha.

Not to dump on your gear, but for couloirs--even iced-up ones--you'd get much better traction and economy from mountaineering crampons. Vertical frontpoints, especially mono, are mostly decorative on snow and work your calves harder on low-angle ice.

Way to get after it!

Yeah these crampons definitely have their shortcomings in terrain like this. Acquiring proper mountaineering crampons that actually weigh less than a pile of bricks is definitely on the agenda for me.

I never thought I'd see the words "October" and "couloir" together...
Good job getting it done!!
