Snowpit Observations
More detailed information about the snowpack: 

I walked up an over Wheeler Peak to get a look at some deeper pockets of snow above treeline on N and NE aspects.  In many places, only last week's snow sits on the ground, but in the isolated pockets of terrain with the deepest snowpack, facet/slab combinations exist above a thick layer of depth hoar.  In some places the most recent wind slab was punchy, and in others it was completely supportable.  I did not encounter any cracking or collapsing in the snowpack.  Stability tests confirmed that the layer of most concern in the snowpack is weak, faceted snow lower down in the snowpack, and that propegation in this layer is possible.

Photo 2:  Snow coverage on N and E aspects in the Williams Lake area.  The places with the deepest snow are the same places where instability exists.
