Quick report

Great skiing, soft fluffy snow, in trees on N aspects above 8,500ft elevation. Low tide up to ~9,000-9,500ft, then good coverage higher. South and west aspects were all crispy. Wind board, wind crust, and low-tide-scoured ~11,000ft and higher. Dug a pit with 175cm of snow on N aspect at 10,200ft. 40cm of loose facets on the bottom, but were rounded and wet. ECTN15 at 100cm. Inconsistent break, did not propagate. Saw an avalanche at 9,900ft going off a rollover into the gully, which look like it slid on ground level, maybe during the storm last week.

Rollover that was probably getting a lot of wind slid essentially to the ground, 50ft long into gully, several hundred feet wide. Guessing it was during the storm cycle, but could have been Wednesday night during the storm cycle, or other timing.
