Snowpack Summary

Recent warm weather has made the surface moist, especially at upper elevations. Below the moist surface, about 30-50 cm snow overlies a thick crust that was buried on January 6. This crust exists up to about 2000m. Mid and lower snowpack layers are considered well settled and generally strong.
