On Friday, there were reports of several natural and explosives triggered avalanches to size 2.
5-10 cm of recent storm snow is sitting mainly on wind slabs and facets (sugary snow), as well as surface hoar (feathery crystals) in sheltered areas and a crust on sun exposed slopes. There are up to three layers of surface hoar that were buried in mid and late January, and early February. These layers are around 30 to 80 cm deep and are most prominent at lower elevations. The surface hoar may sit on a crust on south facing slopes. The most recent reported avalanches on these layers have been on the early February layer. These reports have been mainly from the western portion of the region, near the boundary with the South Columbia region. Avalanches on these layers are infrequent, however it may still be possible to trigger an avalanche on these layers in isolated areas such as steep cutblocks, large open glades and south facing slopes.The base of the snowpack is composed of weak and sugary faceted grains that sit on a crust.
