Snowpack Summary

The freezing level on Friday was hovering around 2200m in most areas. Slight cooling overnight coupled with mostly cloudy skies will likely result in the formation of a thin surface crust that will break down during the day on Saturday. At higher elevations, new snow and wind have likely formed small wind slabs and cornices remain large and looming. The snowpack is well settled and continues to transition into a spring snowpack. The December facets and November rain crust are buried deep, but have not been reactive for a few weeks.
