Going to need these again very soon.
Anti-crevasse skis I developed for glacial travel. I used them on most of my winter climbs in the Alaska Range. They are made of steam bent yellow birch from my homestead in Minnesota. They are 5 inches wide at the shovel, 4 inches wide at the tail and 82 inches long. They have about an inch of camber.
The bottom is coated with a two part epoxy for strength and durability as well as a good base for glueing on skins. The tops are pine tarred. I use a Voile switch back binding that will accept most mountaineering boots.
The length and width of the ski help spread out weight to better handle the majority of the crevasse snow bridges in winter and also the deepest snow.
