Loose snow avalanches have been reported in steep terrain.

10-20 cm of recent snow (more like 30 cm in Kokanee Glacier Park) overlies a layer of surface hoar buried around Feb 12. This burial depth is still shallow, and for the most part the snow above is still light. However, there may be isolated slopes where the wind has blown the new snow into wind-stiffened deposits sufficiently deep to create a potentially harmful slide. Additionally, the well-developed crystals associated with this weak layer indicate it is likely to stay with us for a while and present bigger problems as it becomes more deeply buried. Two previous buried surface hoar/facet/sun crust layers 30 and 50 cm below the surface (Feb 4th and Jan 23, respectively) are still being tracked by professionals but have not been reactive recently. These layers may be worth investigating on a safe, representative adjacent slope if you are considering riding in aggressive terrain.
