On Friday there were reports of natural and skier triggered slab avalanches to size 1.5 in the Kootenay Pass area. They occurred on north aspects and are suspected to have run on the November 28th surface hoar.

Recent snowfall accumulations across the region have been highly variable; however, as of Friday some areas had upwards of 30cm overlying a variety of surfaces which may include weak surface hoar crystals, a sun crust on steep solar aspects, and well settled storm snow from last week. Forecast wind and snow will add to the size and reactivity of this developing slabIn the mid snowpack there may be a spotty, thin buried surface hoar layer between 50 and 80cm down. At the base of the snowpack sits the early November rain crust. Located about 100cm below the surface, it seems most likely to be found in deeper snowpack areas and may have associated facets. These layers seem to have been unreactive in recent days, but may have the potential to 'wake-up' with forecast loading.In general, snowpack data is sparse in this region and significant variations likely exist from one drainage to another. In short, digging down and making your own observations will be critical to safe slope selection. Any observations from the field are welcome at [email protected].
