More detailed information about the snowpack: 

Wind slab was actively forming throughout the day from snow blowing from the west side of West Willow Peak. This wind slab was most notable within the top 40 feet below the ridgeline of the leeward side. We observed a shooting crack about 10 feet long while skinning up the ridge and choose to turn around. The new loose snow from the past storm is 10-30cm deep on top of a hard crust. The new snow was developing a harder wind affected layer on top, in isolated areas where the wind was depositing snow. While leaving the area, it was easy to ski cut small wind affected slabs (10cm in depth) on the eastern side of the ridge above the road.
