  Problem 2 Comments: 
STABILITY TESTS
 Stability Test Results: CTM 15 SC 24cm from ground; Hand-M at same layer (stability test from non-wind-loaded area)
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)   Length: 1 m
 Collapsing (isolated) Depth: 20cm from surface Length: 1 m
 Comments: Collapsing and cracking observed in 38 degree N facing wind-loaded chute near top of peak 9920 (N pk of Baker Pk)
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: HIGH Trend: Improving
BOTTOM LINE
 Comments: Steeper wind-loaded areas could send you through the cheese grater. Chose to ski a lower-angle line in NE bowl of Baker Pk, rather than the line of ascent due to the wind slab. Even with careful skiing, still nicked plenty of rocks. Donned skis at 8800' on ascent (N aspect), off at 9300' on descent (NE aspect). Winter is still a ways off.
