Did you see shooting cracks?

Yes, Isolated

Did you experience collapsing or whumpfing?

No

Found wind effected conditions throughout the north slope, with localized shooting cracks and wind slab. Wind slab and shooting cracks were also present just SW of the apron of the Circus Couloir. Most open, unsheltered north facing terrain was fairly wind effected, though the avalanche problems seemed isolated to specific features.
