Snowpack Summary

Last week's snow is settled and is bonding to the old surface up to treeline elevations. Alpine areas around Squamish likely received about 60-100 cm of storm snow and more wind last week. In these areas the storm snow is possibly sitting on a mixture of weak grains including a crust on solar aspects and potentially facets/surface hoar on polar aspects. Below the storm snow the snowpack is generally well settled and strong.
