Rain-Rime Crust
Snow Characteristics Comments: 

yesterdays snow was capped with a rain crust, 1"-1 1/2" with new graupel falling on top.  In the wind, the crust is exposed and crunch, punchy, ie not exactly "stellar" conditions, we limped our way back to truck

Red Flags
Red Flags: 
Recent Avalanches
Heavy Snowfall
Wind Loading
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Increasing Danger
Problem #1 Comments: 

These will be sensitive on rain crust/graupel layer, we also found a clean shear at old snow/new snow interface, no collapsing and no propagation on ECT, likely faceted surface snow from last Friday's arctic temps. 

Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Increasing Danger
Problem #2 Comments: 

surface hoar layer is now 80 cm deep, non reactive to ECT, but still could pose a bigger problem if activated.  with weekend's 1.7" of H2O and continued storm, time will tell
