Quick report

Cracking
isolated

The 6 inches of new snow near treeline provided OK turns, but the crust below is felt while riding.  Lower-density storm snow at the crusty interface could create a small, soft slab problem if overnight weather forecasts verify.  I would guess that well-drifted features at higher elevations pose a small, soft slab problem.  Slopes without wind-loading steeper than 40 degrees are likely to sluff.

On features steeper than 40 degrees, it was easy to produce loose avalanches in the new snow. I hunted for drifted features in this near treeline zone and only produced short running cracks.

About 6 inches of new snow at treeline. Occasionally gusty winds transporting snow in open areas.

Snowpack

Storm totals around 6 inches at 1 pm near treeline.  There is lower-density snow near the crust interface with denser snow above, including a graupel layer at the surface.  I didn't encounter any significant wind loading in this terrain, but leeward features were top-heavy and produced short cracks.  Today's easy sluffing on steep features could produce shallow soft slabs with more snowfall, or wind slab issues on well-drifted features at higher elevations.

A couple small, loose dry avalanches on the steepest features in this area.
