Date: Dec 12th, 2014
Weather:
Partly cloudy, some fog, winds <5 knots.
Obvious signs of instability:
Recent Avalanches – Yes, singular, small natural point release.
Collapsing – No
Cracking – No
Snow depths:
0-2000′: none (estimated from air).
2000′-4800′: 0-7’+.
4800′-6000′: Unknown, dug snow pit down to 6 feet depth.
Primary concerns:
Top 4″ sluff release (CT12)
Weak slab layer at 20″ depth (CT16)
Fall would cause injury due to rock and glacier ice wedges sticking out at
base of couloir.
