Kootenay Boundary

A weak layer of surface hoar (feathery crystals) exists down 30-50 cm. This layer is most pronounced at treeline and below. Keep it in mind in areas such as cutblocks and open glades where layers like this could catch people by surprise.

Several explosives triggered storm slab avalanches to size 2 were reported on northerly aspects on Wednesday.No new avalanches were reported in the region on TuesdayOf note, a remotely triggered (triggered from a distance) size 2.5 avalanche was reported on Saturday on a southeast aspect at 2150 m. The avalanche occurred in a terrain feature where the snowpack varied in depth from deep to shallow.

30-50 cm of recent snow has fallen in the region. This snow sits on surface hoar (feathery crystals) in shaded areas that are sheltered from the wind, thin rain crusts in some areas, and sun crusts on south facing slopes. The surface hoar is most prominent at treeline and below. Recent snowpack tests suggest that the snow may be poorly bonded to these layers in some areas. Another prominent weak layer in the snowpack is a layer that formed in early December and is buried approximately 70-110 cm. This layer consists of a rain crust, surface hoar, and facets (sugary snow). There have been no recent reports of avalanches on this layer, however a large load, such as a cornice fall may still have the potential to trigger large avalanches on this layer.
