Snowpit Observations
More detailed information about the snowpack: 

Below treeline our snowpack is quickly settling and we are finding very shallow snowpack overall (40 to 65 cm).  In areas our snowpack is showing signs of strengthening during this week plus long high pressure with warming temperatures.  Other slopes are not healing as quickly.  Very big 7-9 mm surface hoar in open areas below treeline, and widespread near surface faceting on others.  Above treeline there are slopes with firm wind packed slabs on the surface.  South aspects had sun crusts.  The potential for new snow on Tuesday Night will be falling on a variety of surfaces.

We're not finding depth hoar everywhere, but when we do we continue to get moderate to hard force to collapse the facets with propagation.  Some slopes have a graupel layer higher up in the snowpack that we were able to get to propagate with easy to moderate force when a cohesive surface slab was above (See Video).  Some slopes have several graupel layers, that are showing signs of healing, but not everywhere.

Photo 2:  NE aspect above treeline showing a couple of graupel layers in the snowpack.  Video was shot at this snowpit.  This slope has slid a couple of times during avalanche events earlier in the year.
