On Sunday, there were reports of numerous natural, human and explosive triggered storm slab avalanches up to size 2.5 at treeline and in the alpine on all aspects (see this MIN report).On Saturday, explosives triggered small (size 1-1.5) storm slab avalanches up to 30 cm deep. Skier traffic triggered small pockets of storm snow with the deepest (up to 40 cm) and most reactive deposits in specific lee terrain.Numerous small loose wet avalanches were observed on Friday during daytime warming.

10-35 cm of recent storm snow that fell over the weekend sits on a melt-freeze crust on all aspects except for north facing slopes above 2000 m, where it sits on dry snow and surface hoar (feathery crystals). Recent snowfall amounts taper quickly below treeline.
