Avalanche Problem #1
Type: 
New Snow
Trend: 
Decreasing Danger
Problem #1 Comments: 

Some (soft) storm slab movement on steep leeward slopes, a little surprised to not see more connectivity in my location (ENE from Catherine's up to Rocky Pt.).

Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 

Dug a pit ~30ft off the ridge, ENE facing at 10,300 ft and found very weak NSF layer sitting on a pencil-hard crust from November, ~40cm from the ground.  This layer caused Sudden Planar ECT results on isolation.

Both the dirty early season crust layer and the (higher) pencil-hard suspect crust visible.

Sudden Planar failure on isolation, near surface facets sitting on top of pencil crust ~41 cm from the ground.

Less connectivity than expected in the storm slab, no observed step-downs to older layers.
