Snowpack Summary
The series of recent storms has left us with around 50-80 cm new snow. Strong to extreme SW winds on Sunday created wind slabs at all elevations, which may now be buried by Sunday night's bonus snowfall. Recent storm snow overlies a hard rain crust. A weak layer from early December consisting of crust, surface hoar, and/or facets and is typically down around a metre. Around 20-30 cm below this interface is a rain crust from mid-Nov with a thick layer of facets below it. Both the early-Dec and mid-Nov layers are probably being capped at treeline and below by the more recent rain crust layer. However, these layers may still be reactive to heavy triggers such as cornices or smaller avalanches stepping down.Â
