Scattered snow showers, light to moderate at times. Light blowing snow observed.
We ascended the road up to around 4,300ft. As we gained elevation we found more and more wind thickened snow. At around 4,000ft while breaking trail in a deeper drift, we had a loud sudden whumph! and a slope about 60ft around us collapsed. It was starting and quite large.
Digging down, we found about 20" of drifted snow over a mix of facets and melt forms buried on January 30th, resting over the stout crust from the 20th. This layer produced results with compression tests as well, even though the slope had already collapsed (CT11 SC).
A little higher and further away we found a very thin rain freezing rain crust overlying very weak facets over the stout crust. Here we were able to get very long shooting cracks in wind drifted road cuts (up to 100ft long or so). This facet/crust sandwich was quite prevalent as we traversed the road near the top of the clearcuts. We ran into some other folks who had skinned directly up the slopes to the upper road we were on. They experienced some 'tree shaking' whumphs on their way up once gaining the ~4,000ft elevation.
