General Comments

new snow was falling on solid melt/freeze crust with little to no bonding occurring. new snow was heavy and dense, forming soft slabs and was easy to slough and run. I watched my partner make 2 ski cuts at the top of a roll over with no results, he made 2-3 more turns and was caught by his slough. It caught and carried him a short distance. he was uninjured and only pushed a short distance.
