You can brave breakable crust down low, to access reasonable conditions at Treeline. Alternatively, you might choose to hone your skills in the new Avalanche Transceiver practice area, on the right just before the Little Prairie trailhead.
Weather Forecast
Sunday: Snowfall (5-10cm) ending early, some sun may poke through in the afternoon. Moderate SW wind, increasing. Freezing level 1500m.Monday: Becoming cloudy, scattered flurries. Moderate SW winds. Freezing level 1400m.Tuesday: New snowfall ( 5 - 15 cm forecast). SW winds becoming Strong-Extreme. Freezing Level 1600m.
Snowpack Summary
New snow/wind fuels Wind Slab development, over breakable crust below 1900m (but to the alpine on solar aspects). A older, cohesive slab below has produced Moderate, Sudden test results on a Persistent Weak Layer (PWL) down 60-90cm (crust on sunny slopes, facets in sheltered areas between 1700-2150m, basal facets in shallow snowpack areas.)
Avalanche Summary
On Friday a few Small - Large (Size 1 - 2) Storm Slab and Loose Wet avalanches were observed, mostly near the divide. On Thursday, Several Small - Large avalanches were observed in steep paths Below Treeline. They were mainly Loose Wet, triggered by rain. One was a Deep Persistent Slab, releasing on ground in a thin snowpack area.

Problems
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
