Pay attention to the direction of the wind as you travel through wind exposed areas.
Recent snow and moderate winds have built new wind slabs over older wind slabs. Expect these slabs to be most reactive in leeward terrain like ridgetops and cross-loaded features, and where a firm bed surface exists.
Avalanche activity has been limited to small (size 1 to 1.5) wind slabs avalanches since the storm on Wednesday. On Wednesday, there was one explosive controlled size 2.5 persistent slab avalanche at treeline. It failed on a 50 cm deep layer of facets sitting on a crust that formed mid-January.
As the wind continues to blow in the coming days, wind slab avalanches will be the main concern.
Up to 30 cm of snow from earlier this week has now been redistributed by predominantly west and southwest winds. This likely sits on previously formed wind slabs. A melt-freeze crust can be found below 2100 m. It may be on the surface on windward slopes and buried 35 to 60 cm in lee terrain.
The middle of the snowpack is consolidated. Weak faceted grains exist near the base of the snowpack.
The average snowpack depth is 130 cm. Up to 200 cm can be found in wind-loaded areas.
