More detailed information about the snowpack: 

Video: Spread out horizontally across a cold N aspect slope, 7 out of 9 ECTs propagated on the NCF layer that remains angular and weak at this location. Test profiles located at the bottom of Powderhouse Bowl, where cold air is most likely to pool. Mid slope on similar aspect, most CTs showed sudden collapse on same layer, but no ECTs propagated - likely due to slightly more solar input and lack of cold air pooling.

Moderate overnight refreeze and cool temps due to light E winds throughout day, though solar input was quite strong.
