Avalanche Observation : February 06, 2010
Date:
February 6, 2010 Observation Type:
Avalanche Observation
Route:
Skier's left Mammoth Rock Chute
Weather:
Cloudy, unusually humid conditions, almost no wind
Avalanche Activity:
We ski cut the top of the chute, and got a small pocket to release. After two more ski cuts, the entire width of the chute fractured (8" crown) and quickly avalanched. Virtually all of the new snow was cleared from the couloir.
It left behind a firm bed surface that could be problematic in the future.

The chute filled in well after the last storm, and the downed tree that is usually visible in the middle of the couloir is buried.
