On Friday, several natural storm slabs were reported on north and west aspects in the alpine and at treeline.
On Wednesday, a small 20 cm deep slab was triggered by a snowmobile south of Valemount. It failed on surface hoar from mid-December that was preserved on a northwest aspect in the alpine.
30 to 50 cm of snow has fallen this week. At upper elevations, southwesterly wind has redistributed snow to lee features.
A surface hoar layer is now buried 40 to 70 cm down. This layer is spotty and hard to find. It is mostly not triggerable, but in very sheltered treeline and alpine features, it may be possible. Where there isn't surface hoar, there is likely a crust.
