Snowpack Summary

10-20 cm of recent snowfall (possibly a little more near Kokanee Glacier Park) overlies a recent layer of surface hoar buried around Feb 12. We have had some reports this layer contains crystals up to 30mm in some locations. This large size of crystal increases the likelihood this layer will present problems as it becomes more deeply buried. Expect to see wind slabs in exposed areas. Two previous buried surface hoar/facet/sun crust layers from Feb 4th and Jan 23 are still being tracked by professionals but have not been reactive recently. They can be found approximately 30 cm and 50 cm below the surface, respectively. These layers may be worth investigating on a safe, representative adjacent slope if you are considering riding in aggressive terrain.
