The Wind and The Roller at Klein Pollux
Why this steep, exposed line above Gorner Glacier demands patience, perfect timing, and a deep respect for the wind.
Hidden beneath the Pollux mountain lies one of Zermatt’s cleanest, most rewarding lines—but only for those who know how to read the wind. From the terrifying "roller" drop-in to the hidden rockfall dangers of the melting glacier, this is a story of learning by doing, the risks of sluffs, and why this adventurous tour remains a superior, quieter alternative to the crowded Schwarztor.
The Cleanest Line Near Zermatt
Under the shadow of the Pollux mountain lies a steep line that many skiers walk past without noticing. It’s called the Klein Pollux, often linked with the Schwärze bowl below. When it’s in condition, it’s one of the cleanest, most enjoyable alpine lines in the region.
It starts with a big roller—a steep, convex drop-in that gradually opens up into a full 40-degree slope. Then, it mellows out into a perfectly flat exit. If the conditions are right, you can really build speed here, carving long, fast turns from top to bottom with almost no effort.
But "if the conditions are right" is the key phrase. This line is selten selten—rarely rare. It only comes into condition in the late winter months, around late March or April. Early in the season, the strong winds pack the snow down into a hard, unrideable crust.

The Wind’s Deception
The tricky part for me has always been underestimating what the wind can do overnight.
You might look at the face from the Gornergrat during the day, and it looks perfect—soft, inviting, ready to ski. But you go the next morning, and the wind has packed it down completely. Sometimes it’s rock solid. Sometimes the wind only blows on the summit, leaving the rest of the face soft. Sometimes the first 100 meters are wind-packed, and the rest is powder.
I’ve found it hard to tell how much damage the wind has done until I’m right there on the face. You have to be willing to walk up, inspect it, and sometimes walk away. That’s the game with exposed lines like this: you don’t know until you’re there.

The Sluff Danger
The stakes here are high. The line is concave, meaning if you get caught in a sluff (a surface slide of loose snow), it funnels you straight toward a drop into the Zwillings Glacier. Getting caught in a big sluff here can be fatal.
Because of this, I usually keep to the skier’s left, even if it means traversing into slightly steeper terrain with a later view of the face. It’s a trade-off: a bit more exposure on the climb for a safer line on the descent.
Over the years, I’ve seen big enough sluffs to carry a person down. I’ve witnessed people falling on this line, sliding fast toward the big drop. I remember one time, watching a skier lose control, and I genuinely thought they were going to slide all the way over the edge. Luckily, they didn’t. But it was a stark reminder: the main error wasn’t the snow, it was a lack of skiing ability to handle such a line. This isn’t a place to learn—it’s a place to execute.

Learning by Doing
I first rode the Klein Pollux with my friend Charlie back in 2012, during one of our "learning by doing" splitboarding adventures. We were younger, eager, and maybe a bit too confident.
The top face is a big roller that can be a little scary to drop into. Usually, it’s wind-affected, but on that day, it was really good. We dropped in, feeling the speed build, and realized how fun this line could be when the stars aligned.
But we also learned the hard way about the bowl below.
The Schwärze is a big bowl with a few different options. The steep sections here usually require abseiling unless it’s a phenomenal winter—which rarely happens these days. As the glacier has disappeared, it has left behind a lot of rocks that need massive amounts of snow to be properly covered. Without that snow, abseiling is mandatory.

The Lower Sections and The Exit
Once you get past the steep roller and into the bowl, the traditional line offers pretty fun terrain. It’s mellow at the top, then hits a slightly steeper, short middle section. This part is great for two or three high-speed turns before hitting the next flat section.
From there, a beautiful couloir leads down to the Gorner Glacier. This is where you need to be extra careful: rising temperatures, especially late in the season, can warm this section up quickly. I’ve seen wet snow slabs bring down loose rocks here. The sound of rocks tumbling down the couloir is a reminder that the mountain is changing.
The same goes for the classic exit from the Gorner Glacier; it’s getting trickier every year. As more glaciers melt, more rocks are exposed. The last time I rode this line, there were around 15 people queuing at the narrow exit point. With warming temperatures, we saw rockfalls and snow bridges collapsing nearby. It was a chaotic scene.
It’s important to evaluate the weather and snow conditions carefully to plan a safe exit. If the glacier is unstable, you don’t rush. You wait, or you choose a different route.

The Reward of Patience
The Klein Pollux-Schwärze is an alpine adventurous line with three distinct sections and a great variety of terrain. It’s possibly one of the best tours in Zermatt for riders seeking something more adventurous than the standard runs.
It’s definitely something for the more experienced tourers, to be planned carefully. But for those who put in the time, who wait for the right wind window, and who respect the sluff danger, it offers a more exciting and less crowded alternative to the Schwarztor.
When you’re at the bottom of the line, after that quick uphill section to the Schwärze, you feel like you’re in a piece of land only for yourself. Immersed in the beauty and calmness of the magnificent peaks surrounding you, the stress of the climb fades. The wind, the roller, the rocks—they all become part of the story. And if you’ve read the mountain right, you get to ski home with a smile, knowing you earned every turn.
