A friend did her MSc on snow slab shear and the forces were enormous but develop slowly over months. Tens or hundreds of times higher than the max force a bolt can take. especially if the bolt freezes into the ice and moves as a mass with it when it shears. It kind of tells you why when you notice how smooth those slabs are and figure what it was that keeps them that way. I'd be interested in seeing some of that information; very interesting. What kind of engineer are you, Greg? You must appreciate a good PAGE TOP as much as the next guy, in any case.
