Weather

High cloud with times of overcast skies and also times of mostly sunny skies. Winds were moderate at ridgetop with a few gusts over ~40 mph. Near and below treeline, out of the wind, temperatures felt warm and sky cover led to greenhousing of the snow surface on all aspects.

Snowpack

Moist snow out of the wind near and below treeline. We were able to initiate some small Loose Wet avalanches running on the dust crust on northeast, below treeline slopes. They were small in size but they would have easily been able to take a person off of their feet in steep terrain. We did not observe any sign of reactive wind slabs.
