Avalanche Summary

On Thursday, a few small loose avalanches were reported northwest of Pemberton when the sun hit soft snow on south aspects.

Snowpack Summary

Wind from the north redistributed exposed snow into lee features, forming stiff wind slabs. Sheltered areas have the best riding and less chance of slab formation.

A firm crust that formed in early November can be found 30 to 100 cm deep in the alpine and at treeline. Weak, sugary facets have been spotted above and below the crust.

Expect to find 50 to 150 cm of snow, treeline and above, with snowpack depth decreasing rapidly below 1600 m.
