SComments:
South aspects were more reactive and slabs were failing consistently on the crust from 2/17. Ski cut slope, not a ton of propagation, maybe 5” crown and 50ft wide.Observed Avalanches

SComments:
Didn’t get a photo of this one, but it appeared to be a natural, crown ~5” deep but broke wide across an open steep south-facing slope, probably 100ft across.Signs of Unstable Snow
Did you see shooting cracks?
YesDid you experience collapsing or whumpfing?
NoObservations
The 2/17 layer got more reactive throughout the day as temps warms and wet heavy slow loaded.
Also triggered a very small wet slab/wet loose low down on the north side of SE Wright, probably around 4100’ in fairly wind-sheltered north-facing terrain, appeared to have failed on the 2/17 interface as well, no propagation and no cohesive slab but entrained very wet snow.
