Snowpack

Surface hoar is on the surface (size 6  -10mm) in many open areas at all elevations. The sun was melting the snow surface on southerly slopes, a new sun crust can be expected. We traveled up to 7600’ observing wind effect on open alpine slopes and ridge crests. Better surface quality conditions were found in sheltered areas. A west aspect snow pit at 6800’ showed a right-side up hardness profile, soft over firmer snow. We observed both resistant and sudden CT results and 3 crusts within the top 50cm(~1.5ft) ; 

Surface hoar on surface, size 8mm

-CT2 RP down 17cm, 

-CT7 SC down 24cm (1cm above a thin meltfreeze crust), 

-CT18 RP down 30cm,

-CT14 RP down 50cm (below K hard 12/18 rain crust)

-Down 60cm is a (P hard, 0.5cm thick) crust that is decomposing

-1F to P hard snow below 60cm

We observed a couple of older avalanche crowns that likley ran right before the New Year. These slabs broke around one of the buried faceted rain crust.
