From instagram:

"I kicked off a small 6 inch slab on a rollover skiing down east of PK."

"Skied ptarmigan this morning, kicked off a decent sized slab rolling over deer park road cross from avy gulch."

"I got a 2 foot wind slab to crack on a test slope. There was lots of evidence of heavy wind affect. Saw a 5 inch by 20 foot slide in sluice box gully (skier triggered)."

From an email: "Skinned part way up Slushmans yesterday, saw that a chunk of cornice had fallen over the south side of the football field and took a medium-sized slab with it. The debris didn’t make it over the cliffs, but I did see debris further to the south."
