Skier cut wet slab 6" in depth, about 20' feet wide. Rna slowly on the density change. Upon reaching a roll over the first avy slowed to halt but with added weight from the cascading snow, a second avy of similar dimensions released on a SE slope at about 9500' with a 33+ degree slope, which ran a few hundred feet slowly. Enough weight behind it to carry a skier into a tree, over rocks but nothing of severe consequences on this slope. New snow interface 6-14" down, was gloppy and wet from midday heating yesterday or the day prior with the new snow acting as an insulator.
