North Shoulder Chair Peak

April 16, 2022
Type : hike
Length : 10.1 miles, roundtrip
Elevation Gain : 4,740 ft.
High Point : 5,880 ft.

Stefan and I discussed our options on the drive up, and decided to go for Armchair Couloir. We had only skied it once before in 2017 (apparently were the first to ski it), and conditions seemed to be lining up for a second go around - snow depth had built up over the last month and we were hoping the line would still be holding good snow.

As we followed the cat track up Alpental Valley, I realized this was my first ski tour in Alpental Valley this year. I had to think about it; surely that couldn’t be true this late in the year? Sadly it was : a combination of not getting out a lot this year, and just skiing other parts of the Pass.
We progressed onto the skin track and meandered up through the Alpental backcountry, passing a waterfall below mushroom couloir, a reminder that it was Spring despite the cooler temps and new snow.

It was smooth sailing up past Source Lake. The snow was obviously sun effected, however on the skin up the valley we had seen some preserved snow in the shade, and we hoped that higher up Northern and shaded aspects would hold the goods.
We broke off from the Snow Lake skin track, following another track up into Chair Peak Basin. We lost the uptrack at one point, and had to break trail for a bit, but found the track again at the start of the Basin. It was easy skinning up past Thumbtack, and we opted to skin up to the ridge, despite the bootpack already in place for the final section.

Reaching the ridge, we saw a group of two begin their descent down towards Cache Couloir. I have often encountered wind slab on these very aspects in the past, but we found stable snow conditions as we cut in a traverse paralleling the ridge. In fact, the snow conditions were excellent and we had a quick conversation about proceeding to Armchair Couloir - should we just lap the pristine powder, or put in a little extra work and go for Armchair? We ultimately settled on Armchair...

Approaching the Northern Ridge of Chair, I couldn’t remember exactly where the entrance to Armchair was. I opted to head looker’s left of a rock spire and once Stefan reached me, he also admitted he couldn’t remember either. We knew we were close, so we slowly progressed down the other side, and had to cut over skiers right to get into the start of the descent. Mental note, go right of the rock spire!
We skied down the apron towards the couloir and the snow was not great - it was very sun effected and had slid in a number of places. Reaching the top of the Armchair, my hopes of a ski were dashed. There were a number of rocks visible at the entrance, and it looked like all the fresh snow from days prior had slid already. It was an easy decision to bail, given we knew there was great snow a little ways back.

We took off our skis and boot-packed up to the ridge. We could see a steady stream of folks following part of our traverse and then breaking off to ski down to Snow Lake. No one had followed us all the way to the ridge, so we had fresh canvas to lay down some pow turns. Farther down the run, the snow quality deteriorated and it was a mix of crusty snow and avalanche debris.

We opted to stop a ways above Snow Lake and cut in a new skin track to get back to the good powder. There were a number of groups both on the skin track above us, as well as skiing down, so we decided to cut over skier’s right and see if we could lay a track back up without being directly in the line of everyone skiing down.
We were able to find a way through some steeper terrain, and eventually reached our traverse skin track and followed it over a ways before transitioning to ski mode. By now, at least 30 people had skied the slope! But it was big enough that we were easily able to find fresh pow. Before we hit all the avalanche debris, we skied to the right, and skied a fresh line. We were able to find some decent snow and enjoyed the ski down to Snow Lake.

Skins back on, we made our way across Snow Lake and then had a halfway decent ski down to Source Lake before following the skin track back out to the car.
Unfortunately, we didn't get to ski Armchair Couloir, but at least got some good turns off the North Shoulder of Chair Peak. I was amazed by the number of people skiing that same route, but it is a relatively easy get for North facing terrain.
