Avalanche Characteristics

# of Avys:
1
Aspect:
SE (SE,E)
Start Zone Elev:
9300ft
Size:
D2
Type:
SS-Soft Slab
Trigger:
N-Natural
Width:
70ft
Comments:

Lots of small cornice fall and loose snow triggers coming from off the ridgelines (D1 slides). This slide was triggered by a smaller slide. It appeared to be about a foot thick, failed a few hundred vertical feet below ridgeline but in a wind-loaded area. Best guess is that it failed on a density change within the past 5 days storm snow or on the interface buried on Feb 11th.
