Comments
This is for the area right above the Snowbird Cat Skiing operation. Skiing back towards the cat track coming up Mineral Basin. Loading was obvious with heavy winds and cornices. Made a ski cut and the whole chute went. Slow and dense to start but eventually propagated around cliffs 200 ft below. We set off other smaller slides in the lower angle terrain in the same zone also. Anywhere there was a convexity with a rollover - over 30 degrees and above 9,500 ft released and pulled a good sized slab.
