Avalanche Summary
Several skier triggered and some natural windslab avalanches were reported on Friday. Several loose dry avalanches have been reported in steep terrain since Thursday. Windslabs will continue to be reactive to rider triggers.
Snowpack Summary
20 to 40 cm of recent snow overlies a layer of surface hoar (feathery crystals) in sheltered areas and a crust on south-facing slopes. Windslabs can be found in exposed terrain in alpine and treeline elevations on all aspects.
Another layer of surface hoar, crust and/or facets exists 90 to 160 cm deep. Reports indicate this layer is hard to find and likely not a concern north of Highway 5. South of Highway 5 it may linger on north through east aspects between 1700 to 2300 m.
Snow depth at treeline ranges from 120 to 250 cm.
