December 25
Bowman trail, Cabin run, Gobblers, Porter fork.
Elevations, slope angles and aspects
6200-10400', angles over 35°, north and west facing.
Snow conditions
There was no recent snow with a few additional bare spots on the Bowman trail.
Above about 8k, an inch of fresh, increasing to almost 3" at 10k.
Wind damage in the area was minimal but, east facing exposed had obvious viewed scouring.
Lower angled skied well, with light density recrystallized over a supportable base.
Steeper shady slopes sluffing easily.
Road was "fast and fun".
Weather
Blue skies, light wind and moderate temperatures.
Avalanche activity
Ski cutting at the top of the main face(bobslid) produced a point release sluff which was about 6" deep and 10' wide.
It ran on the crusted surface prior to the little December 14 storm.
Ski cutting the flanks initiated additional sluffs.
Talk about "loud powder"!
The sluff widened a little to maybe 20', turned the corner descending a surprising distance of about 1800 vertical feet.
It didn't run into the main gully and left a shallow debris pile.
No other activity observed.
Snow pit
Evaluation
Sluffing was the observed instability.
I'd expect a continuation, with sluffs trenching into older snow in areas lacking deeper layer support.
