More detailed information about the snowpack: 

Our goals for the day were to

1.  Assess the sensitivity of wind slabs

2.  Investigate reports of whumpfing in the Swan Range/ look for buried surface hoar and other PWL's.

3.  Determine if the storm missed us completely.

We didn't find any new snow from the storm.  Sun was prevalent to our north.  There were clouds to the south, but they didn't appear to be dropping any precipitation near our location.

We did find wind slabs along the ridge, but they didn't show signs of sensitivity, either in the pits or while travelling on the ridge.

Although it is showing signs of strengthening, we continue to find a snowpack with poor structure.  We found two different layers of buried surface hoar, but both required moderate to hard force to fail and did not fully propagate in stability tests.  We also found thin layers of facets above and below the Dec. 19 crust.  No collapsing, cracking or whumphing was observed.
