avalanche was HS-U-R3-D3 on N-NE facing slopes above treeline, we viewed two from the same area, both 3-5 feet deep HS, one above cliffs and possibly cornice triggered, the other, the one targeted on the map, was potentially snowmobile triggered.
Forecaster's Comments: Good eyes! The two recent natural hard slabs were reported by riders in the Tony Grove Area on 3-23-11. They naturally ran on 3-22-11 during a windy and productive storm. Listed as Cornice Ridge and Castle Rock avalanches. I had a chance to check out the Castle Rock slide on 3-24... I classified it as a r4 d4, with a 6-10+' deep and ~500' wide crown.... Snowmobile triggered SS listed below was unreported until now.
Thanks....... Toby
We also saw a fresh SS snowmobile triggered on the Easterly slopes below mount Gog at approximately 8600' elevation. This slide was a D2 around 80-100 feet wide, and 8-12" deep
