Peeing as a mini expedition
Claus Lochbihler: Let's talk a bit about the conditions and your equipment. What was the coldest part of the expedition and how did you cope with the cold?
Alexandre Marchesseau: The coldest part was at Kahiltna Pass and and at the Denali. On the day of our crevasse fall, it was at least -20 °C and there was a strong wind blowing. But the worst were the four stormy days in the tent. With wind chill, it felt like -40 °C. Going outside once a day just to pee was like a mini-expedition. You put on all your layers, all your gloves and your ski goggles. Then someone opened the tent for you, you jumped out really quickly, did your business, went back into the tent and the others helped you get warm again.
Did your ski boots ever get dry?
You try, but at a certain point they just stay damp. You're happy if they're at least warm and don't freeze. The best method is to always keep the liners and socks warm on your body - so never take the liners off. I had two pairs of merino socks with me. One thicker and one thinner. One pair on my feet, the other to dry under my armpits - the warmest part of my body. For the night, swap the wet socks for the reasonably dry ones.
Very important: a small towel to wipe away moisture. The liners stay warm in the sleeping bag. If the socks on your feet get too wet, change them again. This worked surprisingly well. If you remove the insole from the ski touring boots, you have more space in the boot, which also keeps your feet warmer. We cut out parts of a rescue blanket and put them under our feet - this warms better than normal insoles in ski boots.
Did you use standard liners or different ones?
Liners from Zipfit. They are warmer and more durable than the manufacturers' standard liners.
You are a passionate monoskier. Most recently even on the Mount Logan expedition, with monoskis that can be split for the ascent. Only not this time. Why?
It was the first time in 15 years that I didn't take my monoskis with me on an expedition. Normally I always ski mono. But on Mount Logan I realized that they are extremely tiring on such a long traverse. And on very steep slopes, you take much more risk on a monoski with a heavy backpack than with normal skis. So I didn't do it this time.
Which skis did you use?
I have a friend who builds skis in the Chamonix valley. His name is Jonno Jacobs. He's originally from South Africa and came to Chamonix, I don't know, 15 or 20 years ago - as a young ski bum. The first time I met him was in a couloir on the north face of the Aiguille du Midi. We were both maybe 18 at the time, it was May. He skied in very directly and totally snowed us in. I was pretty pissed off because it was very exposed. We were young and a bit - let's say - 'territorial' in our thinking. I really snapped at him: 'What are you doing here anyway? You don't even know how to ski here'.
But he was a really good skier. We met up again later in a bar. He came up to me and apologized. Ten years later, he started building skis. So I went to him before Alaska and said: I need something very specific for this expedition. Something very narrow, no more than 77 or 80 mm in width. And as light as possible - but still easy to ski. He built me exactly these skis: with a good shape and beautiful design. They are made of bamboo and therefore extremely light.
