WComments:
Avalanche triggered as we entered the canyon from the E side. Active wind loading was observed on this aspect as we were traveling. Slide was triggered from below and propagated across the canyon and out of sight. Slab was 12-14" thick. Visibility was very low so it was hard to pin point exact size and how far it ran. Neither me or my partner was caught.Signs of Unstable Snow
Did you see shooting cracks?
Yes, IsolatedDid you experience collapsing or whumpfing?
NoObservations
Heavy wind loading was observed on W aspects above tree line. Below tree line instability shifted to E aspects in Little Zig Zag Canyon. Things seem to be very dynamic out there during this current storm. I would be cautious of any wind loaded slope as we move towards warmer Temps tomorrow.
