Snowpit Observations
More detailed information about the snowpack: 

 We received 12 in of new snow from the 3/13-3/14 storm.  It fell on a melt freeze crust that formed from the last few days before the system. Some small hand pits were showing a clean shear on the old bed surface. Recent wind loading was observed which has created fragile wind slabs. We are excited to receive more accumulation with the upcoming storm, but this means we could see large wind slab avalanches.
