On Tuesday, a natural size 2 cornice fall was reported from an East aspect at 2400 m. This failure occurred under the influence of the sun and did not pull a slab on the slope below. In the adjacent region a size 2 slab avalanche was skier triggered on a NW aspect at 2500 m. The hard slab failed 3 m above the skier. There were no injuries. On Sunday, a naturally triggered size 2.5 slab failed on a buried crust. In Glacier National Park, skiers triggered a size 3 slab on a buried crust on an east aspect in the alpine on Monday.

Recent storm snow and variable winds have formed wind slabs at treeline and above. Cornices on ridgelines have grown large, and pose a threat to slopes below.A weak interface buried early April is down about 60-120 cm and consists of a crust on solar aspects, and surface hoar on high-elevation northerly aspects. The slab above this interface may be reaching it's tipping point with additional loading from forecast snow and wind.
