Snowpack Summary

Last week's 60 cm of snowfall has since been transported by strong winds and will become moist on sunny slopes and at lower elevations due to rain on Tuesday and from the sun on Wed-Thurs.

The mid pack consists of settled snow, with the late December crust down 65-90 cm deep.

The lower snowpack is refrozen rain effected layers, which are still moist at ground in places.
