Route & General Observations

Human triggered avalanche. On standard gut approach, released while skinning below summit rocks. I was the first on the slope after the recent snowfall. The windslab broke 100′ above me in rocks near summit. Ran 500′-600′ feet. I was caught and rode 450′. Not injured. Crown was 12-15′. The crown seemed to propitiate down to skiers left, lookers right, into a wind loaded more northern aspect. The slide entrained a large volume of storm snow.

Forecaster Comments

Photos below were taken on Saturday, two days after the slide (credit Joe Kurtak).
Joe was also was able to get some pit data from ~300' north of the lower end of debris. Note: this area had not seen the wind loading that occurred higher on the slope near the crown. The crown was obscured by subsequent wind loading since time of avalanche. Alpha angle = 28deg.
