OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (widespread)   Length: 5 m
 Collapsing (widespread) Depth: 25  
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: MODERATE Trend: Steady
 Comments (aspects and elevations of instability, etc): Skiing was excellent and there is plenty of safe terrain, but as I ski traversed terrain in the lower 30's, ominous shooting cracks appeared. Check morescreeksummit.com for the latest blog posting on conditions.
BOTTOM LINE
 Comments: The next storm will raise the notch. Only small natural releases have occurred. With additional snow it should be expected a significant increase in D2 size releases. I am concern about folks hungry for pow skiing and a weak snowpack atypical of Mores Creek Summit area.
