Avalanche Summary
No recent avalanche activity has been reported. Looking forward, the most likely areas for riders to trigger avalanches are in lower alpine slopes, where pockets of buried surface hoar may exist under a slab of snow from last weekend.
Observations remain limited in this region. If you head into the backcountry, please consider sharing your observations to the Mountain Information Network (MIN)!
Snowpack Summary
Around 10 to 30 cm of snow overlies a hard melt-freeze crust up to 1300 m and perhaps isolated pockets of surface hoar crystals in wind-sheltered openings at treeline and above. At upper elevations, westerly wind has redistributed surface snow, loading lee terrain features.
There are currently no deeper layers of concern.

Terrain and Travel Advice
- Investigate the bond of the recent snow before committing to your line.
- Carefully evaluate steep lines for wind slabs.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
Problems
Wind Slabs
Slabs are most likely to be triggered in sheltered lee features in the lower alpine where pockets of deeper snow have been deposited over a layer of surface hoar.
