Skier's right of Square Top on the nose about 100ft down slid at the roll over. Very close but a little left of the area of the last Square Top accident (broken pelvis as we now call it). The slide went all the way down and over the cliff band at the lower half. Quite a bit of snow was involved. There was a snowboard tracking coming out of the left side of the slide. Eariler in the day I was able to get snow to sluff on the crust underneath but movement was limited. No collapses, no shooting cracks all day.
