Dense Loose

Melt-Freeze Crust
Snow Characteristics Comments: 
Skied high elevation south facing today. Sadly it has formed a pretty stout sun crust. Yesterday it was high density surfy cream on this aspect and today very crusty (see photo).
Red Flags
Red Flags: 
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 
Dug a pit on a north facing slope, 33 degrees at about 10,900 ft. Total snow depth is 95 cm. The buried weak layer was found about 20cm below the surface at 75cm. Most likely buried surface hoar. The weak layer was easily revealed with a shovel shear. This layer failed in a compression test CT4 Q2. I conducted an extended column test with no results, ECTX. The shovel shear also revealed a weak layer at 47 cm but this layer did not fail in any tests. The weakness at 75cm is the layer to be most concerned about right now, and I will be watching it in the days to come.
