Avalanche Problem #1
Type: 
New Snow
Trend: 
Same
Problem #1 Comments: 

Based on some quick shear tests, the primary hazard would be storm slab.  I was able to shear the new snow at or just above the crust in a layer of 1-3 mm graupel.  Shears were in the moderate range and Q2/3.  It appears the snow came in dry with graupel and did not bond all that well.

Avalanche Problem #2
Type: 
Normal Caution
Trend: 
Same
Problem #2 Comments: 

Normal caution, It looks like there might have been some new cornice development at higher elevations, I should know more tomorrow.....

HST = 10".  Crust surface is visible.

Photo below, sluffing at 6,800'.

A short tour to get some of tomorrow's trail breaking done in advance.

Still partial access with additional walking until some of the low elevation snow melts.

Overall I would speculate a moderate hazard consistent with the Skyline forecast but would be concerned about the storm slab sliding above the crust.
