This problem appears to be persisting.  Weak, faceted snow from December is not getting any stronger and is subject to significant temperature gradient especially where shallow.

Comments

Snow structure was even worse in the forest on the Swan Flat (northwest facing) side of the ridge.  I could tell there was a widespread weakness just by planting my pole into the snow and feeling it easily drop a few inches in the loose facets and then stop on the hard and icy Thanksgiving crust. 

Lovely day to spend in the Bear River Range above the big turquois lake.  A couple more inches of light snow from yesterday further improved the shallow powder conditions, and it's easy to get around on a mostly supportable base.
