Avalanche Summary
On Friday, reports of the new storm snow was sluffing from steep terrain up to size 2.
Snowpack Summary
At higher elevations up to 25 cm of new snow sits on a series of melt-freeze crusts (solar aspects) and some smaller surface hoar crystals (northerly aspects). Touchy wind slabs exist on lee slopes and behind terrain features and cornices are huge, threatening slopes below.Deeper in the snowpack (60-120 cm down) a weaker interface exists comprising of crusts, and surface hoar. Earlier this week, very large avalanches were reactive on this interface in the neighboring Glacier National Park. I would practice caution and remain suspicious of steeper, high alpine slopes.
