Snowpack Summary

At higher elevations, winds that have switched from the southwest to the northeast earlier this week. You may find lingering wind slabs on all aspects.

Below the recent snow is a melt-freeze crust, existing on all aspects at treeline and below. The crust extends to mountain tops on sunny aspects. In north-facing high alpine terrain, the surface snow may have remained cold and dry.

The mid and lower snowpack consists of a number of old crusts and facetted snow that continue to be monitored, particularly in shallow snowpack areas.
