Snow Characteristics
Snow Surface Conditions: 
Melt-Freeze Crust
Snow Characteristics Comments: 

A .5 to 1cm radiant crust had formed on all aspects creating challenging but skiable "zipper crust" surface conditions. Face shots with crust fragments were frequent and uncomfortable. 

Red Flags
Red Flags: 
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 

Those facets buried near the ground are not going anywhere soon, but with each successive storm we are adding more mass to the slab on top of them. 

Snow Profile
Aspect: 
Northeast
Elevation: 
9800
Slope Angle: 
33
Comments: 

In general, the surface crust was unrelenting on all aspects and we did not find conditions that compelled us to continue skiing after one run. 

I feel it necessary to say that given the avalanche incidents of the past week, and widespread acknowledgement of our poor snowpack structure, the number of tracks on steep to very steep terrain on the top half of the compass seems concerning.
