Weather Comments
Over the course of an hour (1200 to 1300) the cloud cover grew from 20% to 60% with low, dark clouds rolling in from the south. Also in that hour, the wind shifted from the west to the south, and the scoured northerly slopes finally started to load from the wind. These are the slopes with the concerning glacial crust covered in a layer of facets.

Snow Characteristics Comments

Settlement cones are present in all sheltered locations as yesterday's 8" of 3-4% blower has settled into about 6".  Sheltered, low angle, grassy, north facing slopes offer great riding, but anything near the ridgeline has gotten hammered by the wind.  Height of snow varied from 50-70cm across the terrain we traveled from 8000 to 8800 feet.

I don't expect to see any real avalanche hazard in the Powder Mountain area until the northerlies are loaded by this next storm and accompanying wind.  The facet capped crust will make a slick bed surface when we see a cohesive slab on top.
