Multiple avalanche issues were present deep in Bass Creek on 3/12/22. Wet and slab.
Signs of Unstable Snow
Did you see shooting cracks?
Did you experience collapsing or whumpfing?
A ECT was preformed on a NW facing (30 degree) slope at 6800'. The column fully propagated on ECTP23, a subsequent test failed on ECTP24. The problematic weak layer comprises of a 4F layer resting on a rather granular ice crust 40cm down. Various N facing slopes in the area are displaying older crowns and debris (roughly a week old?).
Later in the afternoon, S facing aspects (around 5900') displayed roller balls and point releases. Woomfing was heard on low angle terrain as well, although this only happened in one area.
Ultimately, we decided to play it safe and head back.
Observed Avalanche Problem #1:
S, 5900', D1-2, likely to trigger, 3/12
Observed Avalanche Problem #2:
NW, 5900', D2+, full planar propagation, could be hard to trigger but chance is there, 40cm down, 3/12
