Red Flags
Red Flags: 
Poor Snowpack Structure

Persistent Weak Layer

See above. Tests indicate bridging in the upper snowpack, but the mess of crusts and facets beneath provide the opportunity for avalanches that could step down to the ground.

Snow Profile
Aspect: 
North
Elevation: 
9600
Slope Angle:

Comments: 

Near surface facets and right side up melt forms bridge over a thin crust 82cm above the ground. Below this is a series of crusts and facets; facets are rounding but some are rather large. Crusts are decomposing with clustered melt forms. There is a distinct, hard crust 25cm above the ground that crumbles readily when prodded.
