Snowpit Observations
More detailed information about the snowpack: 

Traveled up towards Leavitt Lake to near treeline.  Below treeline hand pits showed moderate shears on the old facet layer about 25cm down with new snow from Jan storms moist as well as facets below.  Above 9,500' about 30cm of storm snow from January 6th and 8th-9th was much drier with a few very thin crusts in the upper 10-15cm.  Hand pits at this elevation had easy to moderate shears within the new snow and still contained the moist facets beneath.  Quite a few collapses and cracking while traveling through open areas and near creek bottoms.  See photos.  Not great visibility when near Leavitt Lake, but could make out mid storm dry loose activity in the cirque and at least one crown - SS-N-R2-D2 above Leavit Lake on high, north facing terrain below rock bands.  With better visibility suspect we may find more evidence of naturals in the area.
