Avalanche Summary
On Saturday, small size 1 avalanches were spotted in wind-pressed features. On Sunday, a few small size 1 slabs were reactive to skier traffic. Loose dry snow is sloughing in steep terrain.A few small wind slab avalanches were triggered by skiers and naturally on Wednesday. These avalanches were reported occurring in steep terrain, at treeline and alpine elevations. The slabs were generally 10 to 20 cm deep.
Snowpack Summary
Around 30 cm recent snow is being redistributed by wind, with the largest impact in alpine terrain and exposed terrain at treeline.Over the weekend, winds shifted from west to east, expect to find new wind slabs on various aspects and in cross-loaded terrain features. In sheltered areas at and below treeline, the new snow has buried spotty pockets of feathery surface hoar crystals and soft, faceted snow.In the south of the region, the lower snowpack is well-settled. In the north of the region, around 50 cm of snow may overly a weak layer of surface hoar or faceted grains.
