Reports from Saturday showed ski cutting in the Bear Pass area producing both slab and loose dry avalanches to size 1.5. Slabs failed all the way down to the melt-freeze crust buried 60 cm deep at treeline on north aspects. No new avalanches were reported in the south of the region. Poor visibility has been limiting observations throughout the region.On Saturday, the strong westerly winds were responsible for triggering a couple of wind slabs up to size 1.5 from north-easterly aspects in the alpine. On Friday and MIN reported a rider triggered wind slab avalanche size 1.5 from a southwest aspect. The person rode out of the avalanche and the crown was reportedly 35 cm deep. Friday also saw a natural cycle up to size 2.5 in the recent storm snow.

Ongoing snowfall is building new storm slabs on the surface under the influence of strong southwest winds at high elevations. The new snow is adding to existing storm totals of 40-60 cm from the past week. Beneath the surface wind effect, the new snow overlies a plethora of old snow surfaces, including a layer of surface hoar existing on high shaded aspects as well as a melt-freeze crust on all aspects at treeline and below.Deeper in the mid-pack, layers of crusts, facets, and isolated surface hoar buried 50 to 100 cm exist from mid- and late-February and a surface hoar/ crust layer from January is buried around 150 to 200 cm. Near the bottom of the snowpack, sugary facets exist in colder and dryer parts of the region, such as the far north. These buried layers are currently dormant.
