More detailed information about the snowpack: 

Went for a tour up into the Wildy Bowl area. A fairly warm and sunny morning quickly warmed the snow surface. On East/Northeast slopes above treeline we found several combinations of hard melt freeze crusts overlaying multiple facet layers. While these facet layers were showing signs of slowly healing, they were still reactive in long column tests. Decomposing slabs were also observed deeper in the snowpack.

While we did not observe any signs of wind slabs, winds had clearly impacted the snow surface above treeline on all aspects. Sastrugi and wind ripples were obvious in open areas. Previous ski tracks were inverted. Winds continue to strip and scour Western slopes more and more, with cross loaded gullies the only terrain holding snow on this aspect. A recent size two natural avalanche was observed in a Western facing gully. It appeared to run into deeper old layers.

A fairly warm, sunny morning quickly changed into an overcast afternoon. Temperatures at higher elevations remained in the upper teens to low 20's. Low elevations saw temperatures reach the low 40's. Winds were moderate out of the West, with gusts into the high 30's. Snow, mostly graupel, began falling around 3pm. Less than an inch of accumulation.
