Snowpack Summary
Around 10-15 cm of moist new snow now covers the previous variable snow surface that consisted of facets (dry sugary snow) and surface hoar in sheltered areas, or pockets of old wind slab and an ice crust in open wind-exposed terrain (depending on aspect). Fresh new wind slabs may have formed in open north and east facing slopes, especially below ridges and behind terrain features in the alpine. There are probably a couple notable crusts in the upper to mid snowpack. The deeper crust may be associated with a weak layer of facetted snow, but may be limited to slopes above treeline. There's limited recent info on this weakness so I recommend digging to confirm the existence of the layer, its depth, and strength. Snow pack depth and snow quality drastically diminishes as you drop below treeline.
