Comments

Observed a snowboarder from another group trigger a size 2 windslab. He pulled his airbag and was only buried to the waist. Avy was on a South aspect at 1900m, triggered on a ~35 deg. unsupported rollover feature. Just before the avalanche our group dug a quick pit on a south aspect at 1850m. We observed a 35cm 1 finger windslab on top of fist. CTE 1 & CTE 2 (SP) down 35cm on density change (faceting DF's).

Also observed 3 size 1.5-2 Na on South aspects in steep start zones. All within the past 24-36 hours from the ongoing reverse loading.
