Wind Slabs in effect!

Today with a slight warming of -22 °C we traveled to Corbin (RAIN GAUGE) to check out the snowpack. We observed several size 2 wind slab avalanches in cross-loaded features that we estimated to be older than 48 hours. We think these wind slabs are more reactive where a facet layer that formed during the drought overlies the December 23 melt-freeze crust. There was a 10 to 20 cm hard wind slab at all elevations that was drum-like and hollow-sounding.
