Notes
From obs., "Activity I observed was restricted to the new snow. A fair bit of loose snow.... Skiers on the E bowl of Blackmore triggered some D1 dry sluffage, running on a crust beneath the new snow.... No s slab activity observed until the wind started pushing more snow around this afternoon. I watched a small (D1) w wind slab build and fail as the wind picked up near the Blackmore/Elephant saddle (happened just before 2pm). S Slab couldn't have been much thicker than 15cm, broke 30-40m wide. These slabs were building rapidly..."
