Report from January 22, 2022

Freddy and I arrived at the Bostock parking lot at 8:15 AM. With the weather being a big ol’ “meh” of poor visibility and questionable snowpack stability, we decided to revisit a classic, the McGill Main Chutes. The area had been closed for two days prior due to highway avalanche control. We figured the run would offer some excellent powdery skiing and remain conservative enough for the hazard at play (several persistent weak layers buried throughout the snowpack). We slogged up the McGill Shoulder through the denser, bushier forest of the Northern Selkirks, staying on the shoulder’s crest. We were trail-breaking the whole time – I bet the groups behind us enjoyed that.

At 1600m (the magic elevation), the trees started thinning out considerably, making route-finding a whole lot easier. While we were trenching through more than 40cm of light and dry powder, the sun pierced through the clouds. What a heartwarming surprise! We could barely see the peaks across the Trans-Canada Highway corridor.

After much effort (and sweat), we reached the treeline where the top of the McGill Main Chutes is located at 2130m. We crossed the shoulder’s crest onto the SW aspect, punching through a few cornices lined up on the ridge. We followed a high traverse, crossing above the Gunbarrels, two straight cleared paths through the trees. Those are awesome options during bouts of heightened avalanche hazard since the potential for large destructive avalanches within this feature is limited.

We dug a test profile to assess the snowpack instabilities. A thick layer of faceted crystals had been buried the week prior. Several natural and skier-triggered avalanches had slid on this persistent weak layer. When our test results showed the layer was stubborn to release, we transitioned for the descent.

During our change-over, we spotted a giant crown along the chute’s top, evidence of past avalanche activity. It was clear the guts would be icy and littered with death cookies but the trim lines on both sides of the slidepath were untouched. The area hadn’t been skied yet (a perk of cutting your uptrack) so we dove right into the first of the McGill Main Chutes.

I followed the crown across the first chute, stumbling a few times on buried debris and ducked into sparse trees to the skier’s right. Boy, was the snow incredible! This is the kind of snow dreams are made out of! We slowed down once we reached the path’s runout. We crossed over the rough avalanche debris and ducked left into the sparse forest.

Ready for lap two, we slapped on our skins at 1600m, where the trees thin out. We wrapped around the shoulder to connect with our original uptrack, now almost icy due to skier traffic over the last hour. We sped up the track, passing a few groups along the way. After all the trail-breaking work, climbing up an established uptrack was an absolute breeze. At 2130m, we traversed again and crossed above the first chute to ski the second. Only perform this traverse after assessing snowpack stability since it exposes you to two huge start zones with serious consequences.

We clipped into our bindings and glided downhill. Again, the snow was sublime. We skied past the avalanche debris and into some old-growth forest that led to a pillowy clearing. I recommend following the slope’s fall line, straight down the chutes. It lines up with the clearing perfectly. Once we hit the Bostock Trail, which is easy to blow past in all the excitement, we followed the trail back to the parking lot, heading SE.
