STABILITY TESTS
 Stability Test Results: CTVQ1(SP/SC) at 25 cm depth, SC-C at 25 cm slab.
CTHQ3 at SH-50 cm layer.
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated) Depth: 20-25 Length: 5 meters
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: HIGH Trend: Improving
 Comments (aspects and elevations of instability, etc): Warming trend and/or solar radiation might result in natural release cycle at SE/S/SW aspects at the 20-25 cm layer.
