Snowpack Summary
15-25 cm of recent snow and light southwesterly wind may have formed small wind slabs on lee features at upper elevations.
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 are generally well settled and strong.
