Snowpack Summary

Only 3-5 cm of wet heavy snow fell on Thursday. This new snow sits on a wide variety of surfaces which had been affected by warming temperatures and variable winds. The degree of wind effect varies throughout the region. Sheltered areas may still have 10-30 cm of powder from previous storms. A variable weak layer that formed in mid-December can be found roughly 20 cm below the surface. This mid-December layer is comprised of crusts on solar aspects and feathery surface hoar in sheltered locations.The lower snowpack is generally well settled with two prominent crusts. The late-November crust can be found 30-50 cm below the surface and the October crust is near the base of the snowpack.
