STABILITY TESTS
 Stability Test Results: ECTN
CT: M Q2 2x's @40cm from surface
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (widespread)   Length: 50m
 Collapsing (widespread) Depth: 40cm Length: 75m
 Comments: Found widespread sensitivity on the faceted layer above the crusts with many collapses and cracks rippling out on cold aspects. Did not get anything to move, but steered clear of slope angles greater than 35*. Saw evidence of D1 avalanches that looked to be a few days old on slopes in the upper 30-40 degree range.
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: HIGH Trend: Improving
 Comments (aspects and elevations of instability, etc): This assessment is based off a short tour with limited observations. It is clear that we have poor structure and sensitive stability conditions at upper elevations on the cold aspects around Titus. The solar aspects and lower elevations don't present the same snow structure and probably have significantly better stability; but with lots of low snow hazards.
