Walking back to my pack I triggered this 1 foot thick slab of ice! The ice formed over a thick layer of facets and fractured just like a snow avalanche. I have never seen anything like this before. You could scoop out the facets with your hand. We were on safe terrain, but it could have been ugly if it pushed you off a ledge. As if we don't have enough to worry about snow avalanches, now we have to think about ice slabs?! Photo: D. Chabot
