Light Snowfall

West
Wind Speed: 
Light
Weather Comments: 
Strong winds and OVC skies to start the morning. S1 Snowfall before 9am. Decreasing clouds and wind after 10am. Sun was very strong once the clouds broke, but the wind and cool ambient temps kept any wet activity at bay.
Snow Characteristics
New Snow Depth: 
12"
New Snow Density: 
Low
Snow Surface Conditions: 
Powder
Snow Characteristics Comments: 
Storm snow had settled to 12" on the southerly aspects of MEG. Northerly facing sported a bit more. But would say that overall HST from Saturday to Monday was around 15" total.
Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Poor Snowpack Structure
Red Flags Comments: 
Observations included handpits, pole probes, and ski cuts. On southerly aspects, there is a 1cm crust buried beneath the storm snow (~30cm) with facets just beneath. Snowmobile triggered P. Slab on NE facing Y Not Buttress at mid elevation. See Avalanche Ob. Winds drifting onto NE facing slopes and cornice formation is prevalent on MEG/MB ridgelines.
Avalanche Problem #1
Type: 
Persistent Slab
Trend: 
Same
Problem #1 Comments: 
Poor structure is still the name of the game and since this zone didn't receive the lion's share of snow, the problem is relegated to convex, rocky breakovers on Northerly facing. Slide pictured below in Y Not is indicative of this issue. Crust/facets on southerly slopes don't have a stiff enough slab to be an issue at this time. Expect this could be different in higher elevation terrain of the upper drainage where winds has created deeper drifts.
Avalanche Problem #2
Type: 
Cornice
Trend: 
Same
Problem #2 Comments: 
Large cornices forming on the ridgeline between MB and MEG above Pagan Basin. With forecasted warming this week, will be giving these a wide berth and limiting exposure beneath.
Comments: 
Photos: 1. Persistent Slab in mid elevation Y Not of MEG. Approx: 3'x45'100' . (Center of frame) 2. Sled tracks all over steep terrain in Y Not and Outhouse 3. Large cornice formation above Pagan Basin 4. MEG under clearing skies
