 1 North of Peak 2 Yesterday 1 U SE 9,200' Small wind-loaded lip at an exposed saddle.
 Comments: Some action from (2/11) wind slabs. Hard to discern what went on during the extended storm cycle. No obvious crowns like in the WRV and Smoky/Boulder zones.
SNOWPACK OBSERVATIONS
 HS: n/o 
 Upper Pack: Wind slab in exposed alpine. At 8,500', east-facing slope: 45 cm settled heavy powder above 30 cm rain layer. Upper half of rain layer was re-frozen, lower half was slush. Lower down the fresh snow thinned and the wet layer thickened. Low elevations were a rodeo of stiff rain runnels.

SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: MODERATE Trend: Improving
 Comments (aspects and elevations of instability, etc): MODERATE in the alpine LOW below.
BOTTOM LINE
 Comments: Generally felt much better about the stability here than I anticipated. Fresh slabs were in expected locations but appeared to be stabilizing quickly. Stripped west-northwest-north on exposed ridges. Some creamy powder in sheltered alpine.
