Snow Characteristics Comments

A trace to 1" new. Of interest is the snow surface underneath the trace of new snow does not seem weak. Was expecting some evidence of faceting, but new snow was well-bonded and could not produce any sluffing in the snow surface on even the steepest of slopes.

150 cm (5') snowpack in upper LCC.

Very dense snow even on upper elevation shady aspects.

Will be brief! Got out for an afternoon tour in upper LCC on the afternoon of the solstice. Got up to 10,500’ Dug a few pits and also looked at the snow at the surface. Found 3 layers of faceted snow in upper 80 cms. I've been watching these layers for awhile now and they continue to gain strength. Q3 shears down 60 cms in layer of mid-pack facets. Hammered away on columns and got no other results. Kicked some wind slabs (from Monday?) and not reactive at all. Looks overall green to me, but the structure of mid-pack facets and depth hoar at the ground may warrant yellow at upper elevations.

Video of my partner identifying weak layers in the upper half of the snowpack. Three distinct, visible layers of faceted snow, but they are getting stronger, and the slab above is relaxed. Since this past Saturday the 17th I have been getting at most Q2 or Q3 shears in these upper layers, scores are in the mid to upper 20's, with no columns propagating with ECTs.
