Quick Observation
We utilized a mostly supportable crust to observe avalanche activity from the recent stormy weather.
Most mid and upper elevation avalanche paths ran early in the storm as dry slabs. Debris generally reached the valley floor and traveled up to 4000 vertical feet. We spotted around 40 crowns spread across all elevation bands.
About half of the paths ran later in the storm as destructive wet loose. Nearly half of these reached the valley floor.
The most impressive debris was from the Rescue/Skiumah ridgeline below Skiumah Lake. Wet Loose debris was 1000+ feet wide, and one lobe reached the historic runout. Several locations had debris piles 20+ feet deep.
The paths off Mt Penrose deposited dry debris nearly to Skiumah Lake and wet debris that covered the entire width of the runout.
The avalanche tab will be filled out in the morning.
