Avalanche Summary
A skier accidentally triggered an small (size 1) wind slab avalanche on Friday on Mt. Joan. Check out this MIN for full details.
Snowpack Summary
Around 2-8 cm of recent snow has fallen at upper elevations. This snow sits on a variety of surfaces, including a crust on sun-exposed slopes, old wind slabs, and up to 20 cm of soft faceted snow in sheltered northerly terrain. In isolated areas, wind slabs may be more reactive where they overlie facets and surface hoar. The mid-pack contains several other crusts and layers of moist rounded grains.
Below treeline, most areas are below the threshold for forming avalanches.
