Avalanche Summary
Several glide avalanches up to size 2 have been observed around the Duffey Lake highway on smooth south-facing slopes. This type of avalanche is usually preceded by a crack opening up on the slope, so avoiding them should be straight-forward. Just don’t linger on or under slopes sporting glide cracks. No other avalanches have been reported.
Snowpack Summary
Recently, wind slabs have developed lee to both SE and down-valley winds. Apart from a couple of strengthening storm snow weaknesses, the snowpack is generally well-settled. Surface hoar layers buried in the upper/mid snowpack appear to be gaining strength but still exhibit hard, sudden results in snowpack tests. Near the base of the snowpack, a crust/facet layer appears to be inactive. A thick layer of facets making up the bottom the snowpack was observed on a north aspect near Wendy Thompson Hut. Although unlikely, triggering an avalanche on a basal weakness may be possible from thin snowpack areas or with a very heavy trigger.
